[BUG] search_mode_toggle_enabled() is not properly working when using get_search_fields()

[roniemartinez]

DjangoQL does not work with autocomplete_fields when using get_search_fields() instead of the attribute search_fields.

This line in admin.py should be calling the self.get_search_fields() instead of self.search_fields:

djangoql/djangoql/admin.py

Line 58 in d5d66e3

return self.search_fields != DjangoQLSearchMixin.search_fields
