Flacky e2e test Submit Enketo form submits on reports tab

[dianabarsan]

This test sometimes fails with this error:

1) Submit Enketo form submits on reports tab
  - Failed: visibilityOf failed in 10 seconds By(css selector, #reports-content .details ul li:first-child p)
  Wait timed out after 10013ms

I've pushed a change to use the clickElementNative in an attempt to fix the flakey ness. As part of this I've also been reviewing the test file the executes before. I think it(docs-by-replication-key-view.js) could be cleaned up a bit but I want to see if this fixes it and come back if need be.

I've just seen this test fail on a very fresh branch, locally:

I think I've found the culprit :)
