Enable "Run Query in New Tab" in SQL Lab (#1343)

* Enable "Clone to New Tab" btn in QueryHistoryTable

Method #1; doesn't feel very clean.

Going to attempt to reimplement using an action and changing state directly
through the reducer rather than creating a new QueryEditor object directly from
the QueryTable

* Move Clone Logic to Action

* Implement PR feedback

* Clean up reducer action; fix bug

Bug => Attempting to clone anything other than the most recent Query for a given
TabbedQueryEditor would throw an exception, because we depended on lastQueryId
to find the title of the QueryEditor to clone. Since you can only activate a
clone from the currently active tab, we can instead fetch the ID of the Editor
to copy the Title of from the tip of tabHistory.

* Tests for Reducer Action

* Fix CodeClimate feedback
