test(jqLite): increase timeout and add a label

This test has been flaky on Sauce+IE.
I think 2secs might be not enough for IE sometimes.
chore(travis): enable SL video recording
chore(travis): increase browserNoActivityTimeout

We’ve seen many failures recently because of Karma killing a browser
after browserNoActivityTimeout. It’s possible that this is not any issue
other than super slow network / proxy.

Will try higher timeout and observe for a while.
