Fix Nova test data and selenium tests

This patch squashes two commits, as the commit issues (broken tests)
were blocking each other.

Fix time in Nova test data

A recent update to python-novaclient seems to have highlighted some
incorrect test data, causing our tests to fail. This patch fixes the
time format.

Closes-Bug: 1567634
(cherry picked from commit d6afbac57f)

Fix Selenium Tests

A recent update to XStatic-Jasmine appears to have altered the class
name that a selenium test was looking for. This patch amends the class
so that the test correctly finds the class.
