music app in image 161 shows odd cover art for empty items

[Victor Thompson]

Currently running the music app v1.3.542 from the store on Utopic #161 with updates to mediascanner2 to "0.102+14.10.20140730.1-0ubuntu1" the app shows icons for some items that are undefined.

The following is shown for the undefined items when they are added to the queue:

qml: Debug: Add track to queue: [object Object]
file:///opt/click.ubuntu.com/com.ubuntu.music/1.3.544/MusicNowPlaying.qml:570:31: Unable to assign [undefined] to QString
file:///opt/click.ubuntu.com/com.ubuntu.music/1.3.544/MusicNowPlaying.qml:582:31: Unable to assign [undefined] to QString
file:///opt/click.ubuntu.com/com.ubuntu.music/1.3.544/MusicNowPlaying.qml:594:31: Unable to assign [undefined] to QString
qml: Debug: Queue: Now has: 1 tracks
qml: Debug: MusicQueue update currentIndex:
qml: {"art":"image://albumart/artist=undefined&album=undefined"}

Affecting mediascanner2, because we need to know what needs to be done to remove these items from the models.

This is very critical if it requires a mediascanner2 modification. We need to know if the errors seen in the app are easily solvable:

1. Music/start tab: Most Genres show an empty/blank cover art for one of their items
2. Artists tab: Most Artists show an empty/blank cover art for one of their items, the count of albums and songs is correct, however
3. Albums tab: An odd "undefined" cover art is shown as the first item
3. Songs tab: Many of the odd "undefined" cover art show up at the beginning of the list
4. Artist's page from the Aritsts tab: The number of albums are 1 higher and each album count is 1 higher. There is an album for each that has the "undefined" cover art and the count seems to be the total number of songs in the library. Also, none of the albums listed have a year.
5. Album's page from the Albums tab (or an album from the Artist's page): The number of songs are 1 higher. There is a song at the bottom for the "undefined" cover art.
6. Now Playing queue: Anything added appears to be seen as "undefined" cover art.

Renumbered the list and removed the last item. That appears to possibly be an issue with whatever old merge proposal I had on the device:

1. Music/start tab: Most Genres show an empty/blank cover art for one of their items
2. Artists tab: Most Artists show an empty/blank cover art for one of their items, the count of albums and songs is correct, however
3. Albums tab: An odd "undefined" cover art is shown as the first item
4. Songs tab: Many of the odd "undefined" cover art show up at the beginning of the list
5. Artist's page from the Aritsts tab: The number of albums are 1 higher and each album count is 1 higher. There is an album for each that has the "undefined" cover art and the count seems to be the total number of songs in the library. Also, none of the albums listed have a year.
6. Album's page from the Albums tab (or an album from the Artist's page): The number of songs are 1 higher. There is a song at the bottom for the "undefined" cover art.
