This PR clears up inconsistencies between the gemspecs of hydra-head and its two child gems. While hydra-head depends on rails >=5,2, < 7, both hydra-access-controls and hydra-core allow for rails components as low as 4.0. This seems like an oversight to me where the two child gems should be made to match hydra-head, but if any application was depending on just a child gem and not hydra-head then this change might necessitate a major version bump. FWIW all three gems are only tested with rails 5.2 and 6.0 at the moment.
Also removes outdated handling of activemodel < 4.2 in unit specs
