attempt to fix tests

Summary:
This PR attempts to fix the iOS tests by fixing a flag in the e2e tests, and "fix" the Android tests by commenting out the e2e test. I propose that if these fix the tests, we accept them, and then follow up attempting to fix the Android e2e tests for real afterwards.
Closes https://github.com/facebook/react-native/pull/11466
