Incorrect display for default exec pin for Switch nodes

The pin for Default for switch nodes in the preview build for 4.16 displays as a circle, this visual display for a pin is used with variables or a reroute node, but the default is and exec pin, and therefore should display as an arrow.

Regression:
This issue occurs in the 4.16 binary preview build

This issue does NOT occur in the 4.15.2. binary build

1. create a new project (no template or starter content needed)
2. Create a new actor class blueprint > Name it "Actor_BP" > Open Actor_BP
3. Add a switch on Int node to the event graph
   Result: The pin next to default is a circle and not an arrow (Screenshot_01)
   Expected result: The pin next to default should look like an arrow (Screenshot_02)
