[AC-1650] [AC-1578] (#3320)

* Upgraded old 2019 plans to have the same features as 2020 and beyond

* Removed redundant test and moved additional test cases to GetByOrgIdAsync_SmNoneFreePlans_ReturnsNull

* Fixed issue where feature flag wasn't returning correct plans

* Resolved issue where getting plans would return a value that LINQ previously cached when feature flag was in a different state
