According to the STOMP spec, the `heart-beat` header is OPTIONAL and a missing header must be treated as `heart-beat:0,0`. Prior to this changen the STOMP implementation would try to directly `.split()` this header value without checking for its existence first. This commit checks for the existence of the heart-beat header and uses the default value `"0,0"` if it's not set. See: https://stomp.github.io/stomp-specification-1.2.html#Heart-beating
