              [with patch, positive review] fix storage of
              GBs for PolyBoRi

Comment:

 the patch is okay.
 Note, that the bug can only occur, when a system is passed, which is not a
 minimal GB.
 However, that's possible.

 In the future version PolyBoRi 0.6 pure reduction can be implemented more
 efficiently without handling sets.
 However, you will need a different workaround there
 {{{
 r=ReductionStrategy()
 if not p.lead() in r.leading_terms:
   r.add_generator(p)
 }}}
