Dont use recovered origin if AH was never found

Problem: After some time in the simulation, I want to search for an horizon. I
do not know where the horizon appears initially when the simulation started. I
therefore leave origin_* and initial_guesscoord_sphere*_center at zero.

By some means later, I have figured out where the horizon will appear.
Therefore, after recovery, I want to set origin_* and
initial_guesscoord_sphere*_center to the origin where I believe the horizon
will appear.

Unfortunately, upon recovery, the new origin_* is overwritten by whatever was
stored in ah_origin_* (this would be zero). Generally, this means that the
initial guess ellipsoid that is setup when a horizon has never been found, is
ill-posed (because the initial (and incorrect) origin_* are used with the
updated initial_guesscoord_sphere*_center).

Solution: Don't use the stored AH origin upon recovery when a horizon has never
been found before.
