Compute lint cache key before linting

Browse source 
Summary: If user changes the file contents during linting (usually when prompted to apply a patch) then we save the old messages to the new file contents. Fix that by computing the hash before linting (or after applying patch).

Test Plan: Changed the file during linting, verified that the file hash didn't change.
