Fix new character actor showing all white on Android.

For android, some settings are not read so they cannot be found when
searching.  This meant some values were set to -1 when poor_man was
not enabled.  This had some weird effects, such as the actor showing
all white for the character creation window in some instances.
Fix is to not change the value of the option if not found.
