t1401: check symbolic-ref failure and --quiet silence on a non-symbolic ref 

git-symbolic-ref(1) documents that reading a name that is not a
symbolic ref fails, and that --quiet does so silently.  Tests such as
t2020 and t5621 already rely on "symbolic-ref -q HEAD" failing on a
detached HEAD, but none checks that the plain form reports the error
or that --quiet stays silent.

Assert that a non-symbolic ref fails with the "is not a symbolic ref"
message, and that --quiet fails with no output.  Use test_must_fail
rather than pinning the exact exit codes, which are documented but not
worth freezing in the test.
