Do not fetch the CL description when using git cl status --fast.

Do not fetch the CL description when using git cl status --fast.

This causes a network I/O, which is not fast. Also this is a non-starter in the
case of no network connectivity, causing a crash instead of completing
successfully. Until Air Canada provides on-flight internet, this is a
non-starter. #firstworldproblem.

Also fix git cl presubmit in case of lack of network connectivity.

it would be neat to cache this non-fast stuff. It doesn't really change that
often, and it's a useful summary to have (for people who have lots of branches).

The funny thing is that gcl does that. It should be added to git-cl one day.
