In copyEdgeNodes the nodes were copied to the wrong places of the send vector. The problem was that the full vector sendProcessNeighborHostAllNodes was used for copying instead of the shorter vector sendProcessNeighborHostAfterFtoC

Only copy send nodes which are not part of the reduced communication (for reduced comm after fine to coarse)

Squashed commit :Fix bugs in edge node routine (x direction)

(cherry picked from commit 1947e09c0590ef29374378fde52e49f09b23a2a2)

SetRecvFsPostDev27() is now called after communication in all directions is finished. This is needed for communication hiding, when cutting the domain in multiple directions.

Avoid calling method to find neighborNodes in every timestep
