Fix check of view updatability in case of underlying view changes its updatability.

Browse source 
For single table update/insert added deep check of single tables (single_table_updatable()).
For multi-table view insert added additional check of target table (check_view_single_update).
Multi-update was correct.

Test suite for all cases added.
