MH-9843, fixes group scheduling options not showing hour and minute labels
Fixing MH-9981, you should no longer be able to deselect all of the tracks during trim.
MH-9843: Forgot the spanish version, fixed the spacing.
Merge remote-tracking branch 'greg-fork/t/MH-9981-disable-all-trim-tracks' into r/1.4.2
Merge branch 'greg/t/MH-9843-recurring-scheduler-missing-labels' into r/1.4.2

Fixed that duration dropdowns were missing the labels "hour(s)" and
"minutes" in the trimming ui.
