Clicking refresh button in Kibana top nav time picker does not cause refresh

[nreese]

timefilter.setTime only emits the events timeUpdate and fetch when called with a new time. Pressing the refresh button does not cause these events to be emitted because the time did not change.

This issue will be less visible once #29674 is complete and the time picker in the global nav is no longer used for discover, visualize, and dashboard.

I tried moving the fetch emit event outside of the areTimePickerValsDifferent but this broke dashboard cancel edit and reverting to old state (specifically the case tested by this functional test https://github.com/elastic/kibana/blob/master/test/functional/apps/dashboard/_view_edit.js#L121 - where you edit a dashboard, add a panel, cancel the changes, and the added panel should be removed).
