cat-file tests: test messaging on bad objects/paths

Add tests for the output that's emitted when we disambiguate <obj>:<path> in cat-file. This gives us a baseline for improving these messages. For e.g. "git blame" we'll emit: $ git blame HEAD:foo fatal: no such path 'HEAD:foo' in HEAD But cat-file doesn't disambiguate these two cases, and just gives the rather unhelpful: $ git cat-file --textconv HEAD:foo fatal: Not a valid object name HEAD:foo Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
