Since b4be74105f (ls-remote: pass ref prefixes when requesting a
remote's refs, 2018-03-15), "ls-remote foo" will pass "refs/heads/foo",
"refs/tags/foo", etc to the transport code in an attempt to let the
other side reduce the size of its advertisement.
Unfortunately this is not correct, as ls-remote patterns do not follow
the usual ref lookup rules, and are in fact tail-matched. So we could
find "refs/heads/foo" or "refs/heads/a/much/deeper/foo" or even
"refs/another/hierarchy/foo".
Since we can't pass a prefix and there's not yet a v2 extension for
matching wildcards, we must disable this feature to keep the same
behavior as v1.
