Item2299: edit-save-rename restores an old version

1. edit a topic
2. save it
3. rename the topic
4. edits gone ... an old version is been restored

Can anybody confirm?

Confirmed on trunk

1. Create a topic in sandbox & save (-> r1)
2. Edit and save (force new version -> r2)
3. Edit and save (force new version -> r3)
4. Rename (-> r3)
5. r3 now shows content from r1 instead of r2.

Unable to replicate on release branch. I have r5389 checked out.

Added unit test, also on release branch, even though the problem does not exist there.

Oh, and fixed the bug. Problem was that we:

1. Load a dummy topicObject with no content for the new topic
2. Move the old topic to the new topic
3. Try to use the dumy topic object, thinking it will magically be updated

And just adding a $to->reload is not enough as there is already a cached version of this dummy topic, therefore $to->{_loadedRev} exists and is set to revision 1, therefore, it will always use revision 1. Fix by:

1. Removing $to->{_loadedRev}
2. Calling $to->reload
