t3407-rebase-abort.sh: Enhance existing tests, and add test for rebase --merge

Removing .dotest should actually not be needed, so just test the directory
don't exist after --abort, but exists after starting the rebase.

Also, execute the same tests with rebase --merge, which uses a different code
path.
