res_pjsip_pubsub: Add body_type to test_handler for unit tests

The ast_sip_subscription_handler "test_handler" used for the unit
tests didn't set "body_type" so the NULL value was causing
a SEGV in build_subscription_tree().  It's now set to "".

Resolves: #335
(cherry picked from commit 71d75373f9df6b971ac069abfbf39be42a1caf70)
