Integration tests are not running

[ilmotta]

Problem

We recently merged #17762, but we missed the fact that the integration tests are not running anymore.

In shadow-cljs, the regular expression looking for test namespaces expect them to end with -test$ by default, but the code we merged don't respect this convention.

Notes

We should probably allow each integration test namespace to run in isolation, thus status_im2/integration_test/core.cljs should not require other integration test namespaces.
