No Net Vias throw DRC error "unconnected end"

Description

Assigning no net to a via in PCBNew will result in a DRC error as KiCAD registers this as having an unconnected end. Expected behavior is to not have a DRC error as the via has no connected ends, which should be appropriate for a no net via, which is essentially a small unplated drill hole of the same dimension as other vias in the board.

Steps to reproduce

1. Place a via.
2. Assign "no net" by choosing the blank text from the net assignment drop down menu.
3. Run DRC.
