adding extractWellPerfProperties to StandardWells

It causes problem for the flow_multisegment. So the version in
BlackoilModelBase is kept for now.

On the other hand, it is few of functions that will be both required by
the standard wells and multisegment wells.

Some decision will be made later on how to put this function.
