tests/jid: fixed crash on QNX

QNX version of printf() doesn't check whether a string is valid or not.
Passing NULL pointer leads to a crash inside strlen(). Fix this with a
wrapper _s() which returns "<NULL>" for instead of NULL pointer.
Add checks before strcmp() to avoid crash in case of unexpected result
of the jid functions.
