        Web Inspector: REGRESSION: Canvas: the first processed action should be selected as soon as it's available if no previous selected action exists

        <rdar://problem/48875214>

        Reviewed by NOBODY (OOPS!).

        * UserInterface/Views/CanvasSidebarPanel.js:

        (WI.CanvasSidebarPanel.prototype._handleRecordingProcessedAction):

        Rather than wait till the entire recording is ready, set the selected action as soon as the

        first action is ready (assuming there isn't already a selected action).
