[PATCH 1/3] t1006: update 'run_tests' to test generic object specifiers

["Victoria Dye via GitGitGadget" <gitgitgadget@gmail.com>]

From: Victoria Dye <vdye@github.com>

Update the 'run_tests' test wrapper so that the first argument may refer to
any specifier that uniquely identifies an object (e.g. a ref name,
'<OID>:<path>', '<OID>^{<type>}', etc.), rather than only a full object ID.
Also, add a test that uses a non-OID identifier, ensuring appropriate
parsing in 'cat-file'.
