For the coarse solver the right hand side has to be consitent
everywhere. Fixed the code to do this.

index of the first vertex is not in the set other vertices of the same
aggregate might be represented there. Therefore we now check all of
them whether they present anf if one is present the coarse index set
will get an according index for the aggregate.

This function is needed in AMG to prepare the right hand side for the
coarse solver.
