Split from {T16862}.
Imagine A@global (composed of A@commonswiki and A@metawiki both attached),:
B- A@global (composed of B@wikidataA@commonswiki and BA@metawiki both attached), C@global
- B@global (composed of B@wikidatawiki and B@metawiki both attached)
- C@global (composed only of C@mediawikiwiki).
Current situation (aftersince T16862 iswas fixed) is that B and C can't be renamed to A. This means that all the users forcefully renamed for {T37707} (if on more than one wiki) will have to request rename on Meta and only RenameUser will help.
However, this means that all such accounts will be unattached, and this is less than ideal, beside being a pain for everyone involved. All such users will be in the case B, because requesting rename creates a local account on Meta, All such users will be in the case B because requesting rename creates a local account on Meta and A will probably have to confirm too.
What we need is:
* C can be renamed to A: C@global is deleted, the local account is
attached to A@global.
* B can be renamed to A: the wikidatawiki account is attached to A@global, while B@metawiki is left behind and B@global stays.
