Fix bug in URI computation in RemoteModule

Also add tests for the CAS path converter. I've also changed the code to
explicitly inject the RemoteOptions into the CasPathConverter - note that
the class is now static, so it no longer has access to the fields in the
RemoteModule class.

This change will need to be cherry-picked into 0.5.2.
