Updating test structure to more effectively test async/sync tests and combine logic to reduce overall integration tests

[BryanFauble]

Problem:

• The repo tests were very flakey and had issues with timeouts, duplicated logic, and causing a disproportionate amount of the Sage GH budget

Solution:

• Remove the need to create a separate suite of async/sync tests and instead verify a few in the wrapper to verify logic.
• Reuse some fixtures betweens tests like table logic so that fewer interactions with Synapse to set up the test cases is required
• Creation of many unit tests to cover lines that were not previously tested, or to verify test cases that were integration tests but did not need to be

Testing:

• Will review test runs, additionally I ran the tests on my local machine to review code coverage and found that they all passes with code coverage now around 80%
