Bug 901102 - enable test_streams_element_capture_reset.html on B2G. r=cpearce
Bug 1076597 - Fix Settings API shutdown race condition. r=bent

When child message manager dies, it sends a child-process-shutdown
message to the SettingsRequestManager. This would just close the locks
and tasks of this message manager. The race happens when some
applications can shutdown quickly: settings requests will never be
committed to the database. One example is the callscreen. The fix,
provided by qDot, simply put those tasks in a finalize state to make
sure they are properly executed and committed.
