GP Add Primitives: Removed the requirement for an active layer

Previously, the add primitive operator (rectangle/circle) required
there to be an active layer present before it would allow you to draw
a new primitive. However, this reduced the usefulness of this tool
(especially if you intended to use these tools to roughly block out
the requried shapes first in a new/blank GP object).

There was no real reason for this limitation, so no, the operator will
create a new layer itself if necessary, just like the Draw operator
has done since day one!
