This module has build errors with Release configuration and is not necessary. When in Chrome debugging mode, a warning will be issued about missing the RCTSnapshot module though, which is why we linked against it in the first place.
The test structure is now provided by a JS API, that is used by all things that run tests. Also, the tests can be run manually by tapping a button in the ReactTests app.
The deleteTestFiles() function is now added to the Realm object, so that it's easy for the RPC module to handle this as well. We can only do this in testing environments in the future.
