Ulan Degenbaev 767fff40e2 [heap] Avoid updating the shared worklist twice in per-context mode 
MarkingWorklistHolder has two references to the shared marking worklist:
1) as a standalone worklist for general marking,
2) as a context worklist for per-context mode marking.

Because of that the shared worklist gets updated twice and breaks
the invariants of UpdateMarkingWorklistAfterScavenge.
