main/config_options: Check for existance of internal object before derefing

A can load and register an object type while still having an invalid sorcery
mapping. This can cause an issue when a creation call is invoked. For example,
mis-configuring PJSIP's endpoint identifier by IP address mapping in
sorcery.conf will cause the sorcery mechanism to be invalidated; however, a
subsequent ARI invocation to create the object will cause a crash, as the
internal type may not be registered as sorcery expects.

Merely checking for a NULL pointer here solves the issue.
