DevTools: Fix async stacks instrumentation for XHRs.

This fixes 2 bugs:
- XHR async call stacks could be deleted too early having the second onloadend
  callback w/o async stacks.
- XHR async call stacks were not deleted at all if there was no onloadend event
  listener attached (aka memory leak).
