PCB_EDIT_FRAME::EraseRedundantTrack() Fix incorrect detection of the new trace boundaries in a specific case. 

It happens if the first segment of the new trace is inside a pad: the other segments are not found.
And the erased trace is not the right trace.

However this fix is more a workaround than a fix: currently the detection of the trace boundaries (BOARD::MarkTrace())
does not work very well for segments inside a pad.
