Prevent passing custom QueryClient instance to ServicesContext

[mlqn]

Description

It's currently possible to pass a custom QueryClient instance to ServicesContext. This should not be allowed as it enables bypassing the error handling mechanism set in QueryCache and MutationCache.

The main challenge in resolving this task is that several of our tests use the setQueryData method of QueryClient. We may need to replace them with waitForData methods, as we have done in several other tests, but not sure if it's the best solution.

Another solution could be to retrieve the QueryClient instance using the useQueryClient hook when passing the component to test, but this might make the code less readable.
