Fix segfault when two nodes that just joined a mesh want to autoconnect to each other.

In this case, we have not exchanged public keys yet. That should not be
a problem, but we blindly pass a NULL pointer to sptps_start() in this
case which blindly dereferences it. Fix sptps_start() by making sure no
arguments are NULL, and teach MeshLink to exchange keys between
reachable nodes when it tries to make a meta-connection.
