Using an incorrect path in a filter causes exceptions

[jgraham]

When invalid paths like /foo are encountered, critic starts throwing exceptions e.g.

Traceback (most recent call last):
File "critic/operation/init.py", line 328, in call
try: return self.process(db, user, **value)
File "critic/src/critic/operation/manipulatefilters.py", line 296, in process
"count": counts[filter_path] })
KeyError: '/webdriver/'

and some others. It should instead handle such errors gracefully,or, if possible, not error at all e.g. by treating /foo/ as the same as foo/.

I think this might be fixed by http://critic-review.org/7fab6a1f?review=117 (which is not on master yet.)

Looks like it works on master now. Closing.
