Test tweaks for compatible security tests (#106464)

Test tweaks for serverless:

* Valid application name in API key tests
* Move from `cluster.health` to `info` call in roles test (the call is just used to check that a user with a cluster privilege is indeed able to execute the test)

Closes: ES-7987
