tests: move non-collapse test out of test-rebase-collapse
The test case was added in
76630fbbf4fa (test-rebase-collapse: Add
test for rebase regression introduced in 12309c09d19a, 2012-01-23). I
think `hg rebase --collapse` was involved in either the regression or
in the fix that caused the regression, but the test that was added
doesn't use `--collapse`, so it doesn't seem to belong in
test-rebase-collapse.t. The test case is about copies, so I moved it
to test-rebase-rename.t.
