typing: make minor adjustments to mercurial/util.py to pass pytype checking

I'm assuming the wrong-arg-count is a pytype bug, because this code is used by
the config object.  Avoiding initializing `_lrucachenode` node points to None
eliminates a few `is not None` assertions, but apparently not all of them.  I
can't figure out why it gets confused over the state where these new assertions
are.
