Avoid RuntimeException passing bogus "service" parameter to Diffusion commit view

Browse source 
Summary:
`PhabricatorRepository::parseRepositoryServicePath()` can return `null` per https://we.phorge.it/source/phorge/browse/master/src/applications/repository/storage/PhabricatorRepository.php;123831b53fb7572cba11e9c990dcb9d247614890$635, thus make the code in `DiffusionServeController:getRequestDirectoryPath()` at least not crash when handling `null` and instead fall back to serving a "403 This repository is read-only over HTTP."

There is probably a cleaner approach which I happily leave to any future person willing to figure it out.

Closes T15944

Test Plan: Go to http://phorge.localhost/rABCD0123456789abcdef0123456789abcdef01234567?service=foo
