safe_z_home: Fix issue where 'home_xy_position: 0,0' did not position at 0,0 

If '[stepper_x]' and/or '[stepper_y]' have a 'position_min' that is
non-zero, and '[safe_z_home] home_xy_position' is '0,0'; then the 'G28'
command will _not_ move to '0,0'; but stay at 'position_min' during the
Z endstop test.

This fix corrects this issue.
