This patch implements the changes in the database required for the
skipped action blueprint.
It just adds a new nullable column to the required tables and add tests
for it.
Note that I am also introducing a fix in a previous tables tests which
will be affected by the changes in the objects.
Implements: blueprint add-skip-actions
