plugins/default: Use local vars for refs

Browse Source 
Since the completion callback (on_switch_workspace_effect_complete) sets
priv->tml_switch_workspace1 to NULL, the unref was trying to unref NULL,
and the reffed ClutterTimeline was not getting unreffed.

This could be triggered by rapidly switching workspaces, switching again
before the animation of the initial switch was done.

Found while working on #2038.
