A temporary fix to address issues with Mxit parsing of messages that have no links attached.
This is necessary once commit 83f08a8 (Add link functionality to REST messages) is added.
(added as a separate commit so that it can easily be rolled back once Mxit fixes their side)
Merge pull request #11 from georgezee/temp-fix-mxit-link-parsing
