patch/remove: add remove sub-cmd

Implement the :patch remove command. Remove a patch set from the
respository and from the internal storage. Note that in git, this will
change all commit hashes that appear after the removed one since the
commit hash depends on its parents. Adjust the code to handle such cases
and add tests for this.
