[fuel-web] invalid usage of mocks in test-cases

[Bulat Gaifullin]

In the following tests uses incorrect methods of mock - object:
TestOpenStackClientProvider.test_clients_providing used method assert_called_with_once that does not exists in mock and automatically creates a mock method that does nothing.

TestOSWLHelpers.test_different_api_versions_handling_for_tenants incorrect test logic, that uses undefined method assert_called_once, that does nothing and test checks nothing as well

to prevent further errors with same cause need to update mock package to version to 1.1.0. or greater
