• Test 1 - ServicePlusDataProvider - Updated to validate the count of data providers registered
• Test 1 - ServicePlusDataProvider - Updated to validate the data providers registered to match the registered Test DataProvider

Notes

Currently failing as there is an issue with Extension Data Providers being registered with their respective service. Depends on

• https://github.com/XRTK/XRTK-Core/pull/871

If there is an issue with the test, please detail it, as the Extension Service and Extension Data Provider have been updated to match what I understand to be the correct pattern, inheriting from the Extension Interfaces. The data provider use has also been updated in the Core and Extension tests to match the real-world implementation we currently have running in our systems (although granted, there is scope for improvement there).

The Core System implementation and it's data providers pass their tests. The same implementation using the Extension interfaces does NOT pass.

Either we need to fix the tests, or change the XRTK extension implementation as it is not currently working as expected.

Will rebuild without dependencies on old PR's
