chore(tests): Remove the unneeded fxa-client.js dependency.
Merge pull request #864 from mozilla/issue-863-test-failure

Issue 863 test failure

A slight break in protocol, I'm self merging. @nchapman did a review and said things are looking good. After > 5 green runs on travis, I'm going to say this is good enough to get us moving again. Will follow on with functional test changes in a separate PR.
fix(client): Redirect to start page if resend email token is invalid.
