test new autocomplete property passing

This change should let us pass autocomplete-specific settings to the
autocomplete plugin without requiring our entitypicker plugin to know
all the properties that might be used, now and in the future. This
should still let us override necessary settings with ones we require and
won't affect our entitypicker specific settings
