any possible reason or explanation for its failing? it seems to be erring consistently

[prabhjyotsingh]

Sure, so basically #1330 solve the problem: "If logged in user does not have Read and Write permission for a notebook, user should not see the notebook in the zeppelin home page."

And the place where this test case used to fail was trying to click on the link on notebook's homepage. Since, after the fix of above issue, the link on which it tried to find and click is not available anymore, it fails consistently.

CI failure on this PR is irrelevant and failing on only build profile.
We might want to open a JIRA issue for it, because that build profile normally have -DskipTest
But seems to fail on a test.

Merging this one quickly to have other PR's CI green

Thank you @corneadoug.
