Fix profile combobox bug
This fixes the bug where when a user edits a StellarSolver profile (in fits-hfr, focus and guide) and the index for the options profile is incorrectly reset to 0
There is a second bug fix in guide, where guide incorrectly uses the focus profile index.
I believe these are confusing enough to the user and straightforward bug fixes which should be included in 3.5.0, but will leave that decision to Jasem.
