Before a 404 would be rendered only after a request to Gitaly would
return with an InvalidArgument error. Now we check that the ref have a
valid format before sending it to Gitaly. In both cases, a 404 is
returned to the user, but this change prevents Gitaly from generating
error noise in production.

This check never worked once the global navigation changes were rolled
out in https://gitlab.com/gitlab-com/gitlab-docs/merge_requests/362. The
global nav will ALWAYS include /ce and /ee links, and the CE and EE
repos will never include documentation for both.  gitlab-docs now
expects the documentation to be in the following directories:

* /tmp/gitlab-docs/ce (CE)
* /tmp/gitlab-docs/ee (EE)
* /tmp/gitlab-docs/omnibus (Omnibus)

The problem is that the CE and EE repos will only include one of the
first two.

Let's disable this check until
https://gitlab.com/gitlab-com/gitlab-docs/issues/305 is resolved.
