Improve TokenService (Crypto Service as well) Code Coverage

[Neeharika-Sompalli]

Add more unit tests to improve code coverage to each class in Token Service

1. Checked box without issue indicates False negative for coverage where codacy reports 0% coverage but test exists.
2. Checked box with Issue indicates the associated issue has been addressed.
3. List items in bold represent classes falling below 80% coverage and targeted for improvement

There are some instances of false negatives for code coverage reported in codacy. See TokenServiceApiImpl as an example where it appears there is no coverage but the test class exists. These classes should be documented and additional coverage should be de-prioritized until we run independent coverage eg. jacoco to support
