[FIX] base_user_role: Improve tests resiliency

These 2 tests were checking the exact set of groups a user should have.

If these tests are ran in a database where a module is previously installed which adds more groups to the base role, these exact group sets would be inexact, although the behavior that is being tested was actually properly working.

With this patch, basically I'm testing if the user contains the groups from the roles, not the exact role set expected. It should work in integration scenarios.
