Error not propagated

[nielsenko]

When running the dart-sdk test-suite with latest realm (v14.7.0), the sync_migration_test.dart suite is failing.

I can one get one of two situations.

1. Either the process waits until the test times out:

2. or, an error is returned, but no error message is set, causing NRE.

The issue was detected on v14.7.0, but I have reproduced with v14.6.2 as well (used in last production release of the Dart SDK).

I assume something has changed on BAAS (we should not be getting: "schema changes from clients are restricted when developer mode is disabled"), that in turn is surfacing this old bug.
