Subject: t6050: redirect expected error output to a file

t6050: redirect expected error output to a file

Otherwise the error from `git rev-parse` is uselessly
polluting the debug output.

Redirecting to a file, instead of /dev/null, makes it
possible to check that we got the error we expected, so
let's check that too.
