[tests] Disable Selenium tests on 1.1 branch

Selenium tests were improved in
56f9955 to make them more resilient.
However, that commit depends on recent changes in openwisp-utils and
cannot be backported to the 1.1 branch.

To avoid duplicating work, Selenium tests will not be executed on the
1.1 branch.
