fix(behaviors): Fix timing of delayed hold-tap trigger 

A hold-tap timer event would be triggered too soon if the hold-tap
was delayed for longer than its tapping-term. This may cause
accidental hold behavior when the correct behavior would be tap.

By queuing the timer event instead of executing it immediately,
other delayed events get a chance to be processed properly.
