Migrated the first of the tests with internal knowledge

Browse Source 
Both test_move and test_orphan needed internal knowledge which comes
with the addition of the "in" attribute. This was in the plan for the
test-revamp from the beginning as it really opens up the ability to
write more unit-style-tests using internal knowledge of how littlefs
works. More unit-style-tests should help _fix_ bugs by limiting the
scope of the test and where the bug could be hiding.

The "in" attribute effectively runs tests _inside_ the .c file
specified, giving the test access to all static members without
needed to change their visibility.
