Tracks not saved unless unloaded

[Sean M. Pappalardo]

On trunk r2277, a new track's analysis results (BPM and overview waveform) are not saved unless another track is loaded into that deck.

Steps to repeat:
1) Start Mixxx, load a never-been-analyzed track
2) Wait for analysis to finish (overview appears)
3) Close Mixxx
4) Open Mixxx again, load the same track, note that it has to re-analyze
5) Load another track into the same deck.
6) Close Mixxx
7) Open Mixxx, load the original track and note that the overview comes up immediately.

We only save track metadata back to the DB when a track is unloaded
from a player, so that's why this bug occurs.

Not high priority...

[RJ Skerry-Ryan (rryan)]

This is provoked by the fact that we don't save data on shutdown, only on track unload. This isn't a problem in the sqlite branch anymore given that I save on shutdown as well. Saving immediately to the DB isn't really an option because of the xrun issue.

[RJ Skerry-Ryan (rryan)]

I'm hijacking this bug -- the waveform would be saved if the track was saved on shutdown -- but in trunk tracks are only saved when they are unloaded. I'm working on fixing this in features_sqlite.

The fix is merged to trunk now, closing.
