Updating tests to reflect validation changes in buster-resources.
Updating tests to reflect validation changes in buster-resources.

Some tests that test the behaviour when a validation error occurs were no longer actually generating validation errors.

Some tests were testing the actual validations present in buster-resources, since they used to live in buster-server. Instead testing generic behaviour for validation messages in these cases.
