TASK: Fix override of runBare() in functional test

[kdambekalns]

As of PHPUnit 11 runBare() is a final method.

This was written ages ago by Sebastian Kurfürst, who recently said:

IMHO we wanted to run each test twice to run it without cache and
then with cache. But it seems this was broken anyways since a long
time – so we can drop it

This is an excerpt from #3405 that fixes just the runBare() override, as that leads to a fatal error when "doing things" with PhpUnit 11…

in case we consider it worth fixing we can get around this restriction of runBare and achieve the same result in a similar way.

For that we would put all generic test functions in a trait and then have two TestClasses both using this trait but having different setup methods. That way we test the same interactions with differently configured views.

jup the StandaloneView thing override also looks kinda hacky :)
