[PATCH RFC 19/20] cat-file: tests for new atoms added

[Olga Telezhnaya <olyatelezhnaya@xxxxxxxxx>]

Add some tests for new formatting atoms from ref-filter.
Some of new atoms are supported automatically,
some of them are expanded into empty string
(because they are useless for some types of objects).
