iOS Player aborts with "!klass->init_pending" during class init when a class implements a covariant generic interface over a derived type

Reproduction steps:

1. Open the attached “IN-148449_Repro” project (The project is nested inside the “IN-148449_ReproProject” folder)
2. Switch to the “iOS Repro” Build Profile
3. Build and Run the iOS Player
4. Observe the XCode console

Actual result: An "Assertion failed: !klass->init_pending" error appears
Expected result: No errors appear
