waveform analysis fails to save and load

[Be]

Waveform analysis caching is broken in recent master. Lots of lines like this appear in the log:

Debug [AnalyzerQueue 1]: Writing waveform from byte array: dataSize 881130 allSignalSize 881130 visualSampleRate 441 audioVisualRatio 100
Debug [AnalyzerQueue 1]: Failed to save waveform analysis for trackId 5092 analysisId -1

This was probably caused by one of these recently merged PRs, or perhaps the combination of them:
https://github.com/mixxxdj/mixxx/pull/1282
https://github.com/mixxxdj/mixxx/pull/1276

This issue is reliably reproducible for me.

Perhaps this is caused by the same issue as Bug #1699023.

I can confirm the "Failed to save ..." logs and will take care of this.

Thanks for reporting! We should have noticed this.

I hope we can detect those bugs earlier during development with more restrictive and aggressive error checking and assertions. The refactored database components already follow this paradigm.
