Diff update osm transportation name network linestring (#996)

Replacing materialized view by a tables with update from trigger on change only.

Differential update of `osm_transportation_name_linestring`, `osm_transportation_name_linestring` and `osm_transportation_name_linestring_genX`).

At the end of the transaction the dependent rows are updated.

It addresses #814 and a part of #809.
