This is so that if MyPy is used in a charm, it type checks them. MyPy by default doesn't type check methods that have no type annotations on them. For example:

$ tox -e mypy
mypy: commands[0]> mypy
src/charm.py:49: error: Call to untyped function "remove_all_revisions" in typed context  [no-untyped-call]
Found 1 error in 1 file (checked 1 source file)

I forgot to do this in #953.

Just a couple of type annotation tweaks forgotten in #953 -- going to merge without further review, so I can go ahead with the release.
