Describe the bug

1. In Fixes part of #5345: Implemented Reset functionality of Platform Parameters with new UI. #5894 there are tests in PlatformParameterControllerDebugImpl which does not project the real conditions and are hard to interpret.
   Regarding test naming:
   Tests are currently named as:

 @Test
  fun testLoadEphemeralFeatureFlags_withOverrideAndNoRemote_returnsDefaultNonOverriddenValue() {

non_overridden_value is a proto field in the EphemeralFeatureFlag.

So here this naming suggests that when the flag is overridden and there is no remote value available then the non_overridden_value has the value of default flag,
Discussion

Would like to hear thoughts from the reviewers.
