set_permissions_globally_command_test: Fix "invalid_regex patterns" test expectations

Testcases are executed in a random order. Unfortunately, this testcase
depended on side effects of other testcases. If this testcase was
executed first, then there were no permissions set and the testcase
would fail.

It now lists permissions before and after the actual test and compare
both.
