Exclude setup wizard for desktop mode home condition

This avoids a timing that ACTION_PREFERRED_ACTIVITY_CHANGED is
on the way (right after setup wizard disabled) but a new task
of next home is launched. The task should be still considered as
a part of home and app handle should not show on it.

Bug: 402779100
Flag: EXEMPT bugfix
Test: No app handle on last step of SUW with desktop mode.
