If certain pjsip modules aren't loaded, the wizard causes a SEGV
when it unloads. Added a check for the presense of the object
type wizard before trying to clean it up.

res_pjsip_config_wizard
------------------
* This is a new module that adds streamlined configuration capability for
chan_pjsip. It's targetted at users who have lots of basic configuration
scenarios like 'phone' or 'agent' or 'trunk'. Additional information
can be found in the sample configuration file at
config/samples/pjsip_wizard.conf.sample.
