repo: remove the last few "pass" statements in localrepo.__getitem__

In case of IndexError or LookupError, we used "pass" statements and
fell through to the end of localrepo.__getitem__. I find the pass
statements easy to miss. Consistently raising and catching exceptions
seems easier to follow.

Oh -- and I didn't plan this before I wrote the above -- that probably
also lets us reuse the "return context.changectx(self, rev, node)" in
a later patch.
