Disable the runtime cache when bootstrapping the tests

[jdreesen]

To ensure that we always load fresh objects.

Note

This is only possible in Pimcore 11.1+

That’s not a good idea: the RuntimeCache is used throughout Pimcore for properties, relations, parent lookups, class definitions, tags, etc. Disabling it for the whole run means every repeated lookup anywhere in your tests re-hits the database or persistent cache instead of being served from memory.
