In of bug 1484496 it was changed that a nsIDirectoryEnumerator is to be passed to nsIFile->GetDirectoryEntries().

It seems this was missed at least at

Found by Thunderbird tests, see bug 1485820 comment 102.

These are the potentially left over occurrences. Compiled on Linux locally.
Please push to c-c and m-c try and see if the change makes sense at all places.

This fixes the test crash we see on Windows in Thunderbird. I haven't done M-C try pushes in ages, so I hope Kris can do that.
Thanks for testing.
I wonder what is the assert/crash good for, if the tests pass fine in opt builds. Is the problem real and are the opt builds silently not working?

It's mostly a sanity check. In this particular case, it doesn't matter much, since we just happen to have two nsISimpleEnumerator vtable entries in this class. It matters in the case of bad casts and missing QueryInterface entries, though.

Please remove this comment. Feel free to just remove the function, though.

Now that the function isn't being overloaded any more you can remove all of the gubbins (keeping just the second line of course).
