Fix RootSystem to use the correct field for determining eigenvectors #4665

  1. FIX: RootSystem now uses the correct field for determining eigenvectors 

    It was  assumed that the DefaultField of the minimal polynomial ist the field to factor it over. In some cases, i.e. x^2+1 for some Lie Algebra over CC (=Field(E(4))) this differs and thus makes RootSystem fail.

Add test to `testbugfix`.
