mq: drop copy records when refreshing regular patches (issue1441)

Copy information was saved in a common loop, then refined in a git-only block.
The problem was the latter did filter out renames occuring in the current
patch and irrelevant to commit. In the non-git case, copy records still existed
in the dirstate, referencing removed files, making the commit to fail. Git and
non-git copy handling paths are now separated for simplicity.
