We downgrade the gradle version to address issues with running jacoco unit test coverage and the realm plugin together.

Motivation and context

Based on tests; if the realm plugin is enabled then jacoco will not instrument classes, leading to no coverage information for those tests. This affects things in the android instrumented tests.

If we disable realm then the coverage succeeds.

If we downgrade the gradle version then coverage succeeds regardless of the realm status.

This is a big enough actual change that downgrading separately to work on the coverage tests is valid.
