Bug 1307015 - Remove CPOWs from browser_bug623893.js r=felipe

Browse Source 
It took me a little bit to understand what the test was doing. It was actually
using the default tab to navigate to three pages. Then, it duplicated it
immediatedly closed that tab. Finally, it duplicated the original tab, then
duplicated the duplicate before closing both of those tabs.
