Schema problems in tests

[finnlewis]

I think @ekes hit some problems with schema so disabled strict schema checking for some tests.

Now we're getting the following:

FILE: ...trib/localgov_openreferral/tests/src/Functional/ResourceTest.php
----------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE
----------------------------------------------------------------------
 39 | ERROR | Do not disable strict config schema checking in tests.
    |       | Instead ensure your module properly declares its schema
    |       | for configurations.
