Intgration tests are failed for Murano dashboard because is_public was disabpled by default

[Timur Nurlygayanov]

We can see some strange fails of integration tests for Murano dashboard:
https://murano-ci.mirantis.com/logs/17/113417/1/check/murano-dashboard-integration-tests-ubuntu-devstack/af9bb07/console.html

so, we changed logic of this in Murano: https://review.openstack.org/#/c/109153/

and now we need to change tests.
