Fixed integration tests

SUMMARY

Due to a change in the receipt of connection parameters in postgresql_privs ( #451 ), fixed the integration tests.

1. Looks like breaking changes were introduced by Fix connect_params being ignored on postgresql_privs #451 to the module's interface. Can users' playbook break the same way after users upgrade Ansible?
2. Also interesting why we didn't get the errors in the original PR...
3. The collection was released yesterday, should a quick fix be submitted to make the stuff working as it did?

@aleksvagachev as #463 seems solving the issue (thanks for spotting the cause!) I think you could cancel the changes in tests here and focus on tidying up the function like removing that param_dict and i think maybe those checks can be also replaced with functions from module_utils.postgres or removed

@aleksvagachev @hunleyd thanks! UPDATE: ah, i mixed up folks, sorry, @aleksvagachev anyway #462 (comment) is still relevant

cool, let's merge it, thanks everyone:) the function can still be improved more as an idea for further contributions.

@aleksvagachev once you're back from PTO, could you please backport this PR manually?
