refactor(oauth): use named tests for WithTenant to improve test output readability

Previously, the test results were printed as #0 #1 #2, which made it
hard to navigate the failed test cases. Now, the test cases
are annotated by their respective names. The names also make it
more clear what is being unit-tested.
