mq: use the editor gotten by "getcommiteditor()" instead of "ui.edit()" (qrefresh/qfold)

This patch also replaces "editor = False" by "editor =
cmdutil.getcommiteditor()", because:

  - it allows to hook commit message determination easily, even in the
    case without "--edit"

  - it avoids regression (or additional care) around saving
    "last-message.txt", even if MQ's "newcommit()" changes its
    implementation logic from "localrepository.commit" to
    "localrepository.commitctx" with "memctx" in the future

    to save commit message into "last-messge.txt" with "memctx",
    "editor" should be valid function.
