fix the TooManyDeletes to show up again

It was moved so it was no longer in the location that
SyncManager expected. I fixed it by (a) moving it to the
SyncManager directory and by (b) changing the SyncManager to
refer to it by class rather than by class name, which means
it will now check for it at compile time, not run time.
