Reverting changes that used Clone() method. This method doesn't copy the  non-persistent data members. The result is that the seeds are affected  and the information used to select the good ones is lost. The number of  multiply found tracks increased a lot as a result.

Additional improvment in the cleanup of the multiply found tracks. Fixes 
in the calculation of phi angles. Fix from the trunk that deals with the 
multiply foud tracks in two neighbour sectors at zero degree.
