copies: avoid calculating debug-only stuff without --debug
`renamedeleteset` and `divergeset` is only used with
`repo.ui.debugflag`, so let's avoid calculating them otherwise. While
at it, I also added a `del renamedeleteset` for consistency.

copies: move early return in mergecopies() earlier
It wasn't obvious that the early return happened only when there are
no copies. That is the case, however, because if `fullcopy` is empty,
then so is `copies1` and `copies2`, and then so is `inversecopies1`
and `inversecopies2`, and then so is `allsources`, and then so is
`copy`, `diverge` and `renamedelete`.
By moving the early return earlier, we also avoid calculating the set
of added files from the base to each side.

tests: test merge of renames of different sources to same target
This is a really obscure scenario, but let's still have it tested so
we know when it changes.
