Summary: hdr script var does not support [0] index

Initial Comment:
When trying to access first element of hdr collection using [0] index <null> is returned. Furthermore,  "DBG:core:pv_get_hdr: index out of range" message is generated in the log.

To reproduce see output of
xlog("L_INFO", "TRACE:TEST: $hdr(Allow)\n");
xlog("L_INFO", "TRACE:TEST: $(hdr(Allow)[0])\n");
while processing any Register message with Allow header. Both log messages are expected to produce the same result. In reality, first log message returns complete Allow header and the second message returns <null>.
