Small fixes to SAPI5

[gexgd0419]

Link to issue number:

None

Summary of the issue:

Some small fixes to the SAPI5 code part that I wrote. Those things didn't cause crashes or obvious errors, so they slipped by.

Description of user facing changes

None

Description of development approach

plibNewPosition is a pointer, so writing to plibNewPosition->QuadPart should be plibNewPosition[0].QuadPart in Python. This is now corrected.

synth.player.idle() is moved to before the "trigger all untriggered bookmarks" part, to let the audio and the contained bookmarks finish first.
