Always match full path in URI Mapper

Summary:
I am not sure if it is by purpose but Phabricator now process paths like
https://secure.phabricator.com/D1681-so-freaking-cool.
The reason is that there are bunch of rules with missing '$' at the end.
This mistake is so common and easy to create that I've rather removed all '$'
and changed the way how the key is processed.
I am not absolutelly sure if the '$' was missing in some rules by purpose but if
it is the case then we should rather add explicit '.*'.
