tests: move non-collapse test out of test-rebase-collapse...

tests: move non-collapse test out of test-rebase-collapse The test case was added in (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. Differential Revision: https://phab.mercurial-scm.org/D7968
