Comment(by mjo):
The whole
{{{
desolve(..., make_it_work=True)
}}}
approach is silly. If we don't get a solution without it, we should use
contrib_ode. If we know the variables are real, we should set domain=real.
It might require a second ticket and some work on MaximaLib/desolve, but
we shouldn't just paper over the fact that this doesn't work (and is a
regression in that regard). Requiring the user to manually set the domain
'''is''' a regression.
