Fix crashing unit tests with regards to RLS.

The unit tests require a sorcery.conf file that has been
set up to store resource lists in memory rather than retrieving
from configuration.

With a setup that is not conducive to running the tests, a fault
in sorcery currently causes Asterisk to crash when attempting to
run any of the tests.

To get around the crash, this adds a function that verifies the
current environment and marks the tests as "not run" if the setup
is not correct.
