Tests require network access

[csomh]

Currently trying to set --network none in make check-in-container causes 65 of the tests to fail (both unit and integration tests), which means, that these tests rely on network access, which means they are prone to failing when an external resource accessed through the network changes its behavior (:wave: Bodhi) or showing false results. With network access one never can be sure that mocks are correct in the tests.

Set --network none in make check-in-container and adjust all the tests to pass without network access.

Still relevant. Would be nice to fix => putting to priority backlog.
