Fix incorrect indexing in `pypesto.profile.profile_next_guess.get_reg…

…_polynomial`

There seems to be an indexing error in pypesto.profile.profile_next_guess.get_reg_polynomial, resulting in too few points being used for extrapolating parameter trajectories. In the second case, not only too few, but also not the most recent parameter values are used.

Closes #1224
