Description
### Bug Summary
Muted tracks' activity indicator is out of sync with notes.
#### Steps to reproduce
Add instruments to B&B editor, make them play the same rhythm and mute some.
#### Expected behavior
Muted channels' activity indicators should stay unlit, or if they're now intended to light up, they should do it in sync with what is playing.
#### Actual behavior
Muted channels light up, later than unmuted channels. This happens in both B&B and Song editors and can be observed across the editors, too.
#### Screenshot

#### Affected LMMS versions
Version 1.3.0-alpha.1.102+g89fc6c960 (win32/x86_64, Qt 5.9.8, GCC 7.3-win32 20180312).
