The patch applies cleanly to the zope.copypastemove trunk, but the test fails for reasons unrelated to the reported bug, as it depends on being able to import, which is no longer a testing dependency. Likely we just need to write a dumb mock container inline in the test (which I would write as a unit test, but that is a de gustibus point).

Added additional check for the same container and the same name after name chooser working.
Unfortunately we can't just move exist check, so need additional check.
Commit into trunk.
