REVISION SUMMARY
  With https://phabricator.kde.org/R293:a75db7aedfcd356b027774e0dc156c334d4cb869 I introduced a crash when removing a watched
  directory. The Problem is that it.remove() invalidates the reference to PendingFile which
  leads to a crash... :(
  I found no bugreport about this on bugs.kde.org until now.

TEST PLAN
  Remove a directory, baloo should never crash when removing a watched directory

REPOSITORY
  R293 Baloo

BRANCH
  fix_crash_pendingfilequeue
