Fix DevTools profiling bailout check

I recently changed DevTools to filter certain types of empty commits (facebook#17253) to avoid showing them in the Profiler UI. I believe this change lead to an increase in the number of 'Could not find node with id...' errors being reported for the Profiler. This commit updates flushPendingEvents() to mirror the bailout check I added previously. This prevents one cause of operations and commit data mismatching that could cause this error. I am convinced there is another case still that I need to fix though.
