Music - Remove from Music/Move to Trash - broken

[Jan Larmann]

Scenario 1:
 - Select any song
 - Right click > Remove from library > Move to trash (should be gone right?) # this(line ^) is what sets the scenarios apart

 - Rescan Music Folder
 - double click on the song you just deleted > press the play button
 - in the far left column where the speaker icon normally appears there now is a round stop sign

- moves file to trash (checked the directory) but does not update list of songs, it still shows up, and I can still play it

Scenario 2:
 - Select any song
 - Right click > Remove from library > Remove from Music
 - Rescan Music Folder
 - there are now two entries of the same song, the one you just deleted
 - looking in the directory of the music, there is only one file per song still though

Another scenario:

- Enable the function to copy imported files into the library
- Import a folder with music e.g. from downloads folder
   -> the files in the downloads folder stay, as expected
   -> the files are copied into the library as expected (folder hierarchy like "albumartist/album/tracknr - title.mp3")
- select the imported files in Noise and delete them (move to trash)
- the files in the library stay, the files in downloads get deleted
