Allow pasting commits more than once

After pasting commits once, we hide the cherry-picking status (as if it had been
reset), and no longer paint the copied commits with blue hashes; however, we
still allow pasting them again. This can be useful e.g. to backport a bugfix to
multiple major version release branches.
