copies: inline _computenonoverlap() in mergecopies()

We now call pathcopies() from the base to each of the commits, and
that calls _computeforwardmissing(), which does file prefetching (in
the remotefilelog override). So the call to _computenonoverlap() is
now pointless (the sets of files from _computenonoverlap() are subsets
of the sets of files from _computeforwardmissing()).

This somehow also fixes a broken remotefilelog test.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
