MGCP_Test: reject empty fmtp strings 

When setting up an RTP flow the fmtp string is checked using isvalue(),
however this does not guard against empty fmtp strings. Rejecting empty
strings is especially useful in situations where the caller wants to
signal using "" that no fmtp string is present.
