error in solving x^4> -2 via solve_rat_ineq

Robert,

I will commit a fix for this problem in the next days (after doing some
checking). 
(My fix takes into account, that the problem is still with algsys and
does not fix the algsys bug 2786017.)

Thanks for pointing to that problem.
Best
Volker van Nek
