rebase: flag --apply and --merge as incompatible

Previously, we flagged options which implied --apply as being
incompatible with options which implied --merge.  But if both options
were given explicitly, then we didn't flag the incompatibility.  The
same is true with --apply and --interactive.  Add the check, and add
some testcases to verify these are also caught.
