Ensure that the status bar test has completely scrolled to top before finishing.

The app can crash due to a bad-access exception in `UIScrollView`
if a scroll view is deallocated before it finishes scrolling to top in response
to a scroll bar tap.

It's also simpler to test that the scroll view content offset changes as we expect
than that labels in the scroll view do/do not become visible.

Unfortunately, it appears as though Travis requires an explicit wait beyond
the wait-for loop.
Disable integration test transition animations when running in CI.

There's no one watching in that case, and disabling animations speeds up the tests
by about 40%.
Move the text field further above the keyboard.

This is the only explanation I can think of for
https://travis-ci.org/inkling/Subliminal/jobs/27273775,
plus the text field tests will look better, though this is still weird.
