Fix region-gain when region is glued to bar/beats

Browse Source 
The region-gain envelop is an Automation list that uses AudioTime
regardless of the regions own position.

Since the actual audio data is using always using samples this
results in reliable envelopes without the reduced granularity of
BeatTime.

All points the list have to be in the AudioTime domain.

Previously it was possible to have a mixed-domain list e.g.

- add 2h:30min long source
- lock it to music-time
- set grid and snap to 1/8 note
- range select some range shortly after 2:25
- draw region-gain for range
