[Bug #18173] Update loaded_features_index

Browse source 
If $LOADED_FEATURES is changed in the just required file, also the
index table needs to be updated before loaded_features_snapshot is
reset.  If the snapshot is reset without updating the table, the
name of the added feature will not be found.
