Bug Description

As per the smart-scopes work and per the fix for lp:1189088, it has been introduced a regression that caused unity to wait 500ms after the user a clicked over an application icon before activating it.

Basically unity waits for a possible double click on every dash icon, and this slows down the activation of application icons using the mouse.

1) Press Super+A
2) Click over an application icon to launch it

Expected result:
3) The dash closes immediately and the app is launched

Actual result:
3) The dash is kept open for 500ms (or slightly more) and finally it launches the

The same happens in the command scope (that you can see by pressing Alt+F2).
This makes the unity dash look slower in launching an app.
