Enabling failOnError flag from waterline-adapter-tests

Version 0.10.5 of waterline-adapter-tests added a flag that causes the test process to fail with an error if the tests fail. Prior versions of 0.10 always returned 0 (a success). This is problematic because Travis bases success/failure of the tests on this return value; effectively short-circuiting Travis as a test-runner.

That said, this PR WILL cause the Travis tests to start failing. These are not errors introduced with this PR, but an unmasking of existing errors.
