[FLINK-3181] [gelly] avoid unnecessary messages in SSSP examples and
library method
I added a simple check in the messaging function to avoid sending
unnecessary messages during the first superstep of vertex-centric SSSP.
Initially, the workset contains all vertices, which means that all of them will
execute the messaging function during the first iteration. However, only the
source needs to generate messages in the first superstep; all other vertices
would produce unnecessary messages with infinite-value distances.
