Get E2E tests running on ScriptureForge again

E2E tests are now running on ScriptureForge after the Protractor upgrade
to 1.1.1 (with its breaking API changes). Two tests still fail when the
whole test suite is run, both of them in the activity page test. They
pass when the activity page is run on its own, but they fail when the
entire test suite is run because they make assumptions about "what is
the last element on the activity page going to contain?" that are false
when the entire test suite is run. Those two tests will need to be
re-worked at some point, but their failure is not due to the API change,
so this is not the right commit in which to re-work them.
