mq: support "qimport --existing --name renametothis thatexistingpatch"

Before this change, the command would abort with a not too clear "patch
renametothis does not exist" error.

This change makes:
  qimport --existing --name renametothis thatexistingpatch
equivalent to:
  qimport --existing thatexistingpatch; qrename thatexistingpatch renametothis
