[Test] Added a test for activeTab URL filtering
Added a test to make sure that changes introduced in crrev.com/2858643002 to ExtensionActionAPI::DispatchExtensionActionClicked work as intended, ie. that the extension doesn't have access to tab.url unless it has the activeTab permission granted.
TEST=This test succeeds with the aforementioned crrev patch, and fails without it.
