Enable DeletingRepeatGroupsTest

[grzesiek2010]

Closes #6078

Why is this the best possible solution? Were any other approaches considered?

It seems something has changed because the tests in DeletingRepeatGroupsTest are now functioning well. I've run each test in that class 300 times on Firebase (150 on API 30 and 150 on API 34), and there hasn't been a single failure.

How does this change affect users? Describe intentional changes to behavior and behavior that could have accidentally been affected by code changes. In other words, what are the regression risks?

It doesn't require testing.
