[2.3.x] No default route on WAN PPPoE after link failure (with FIX, please test)

[cmb]

Thanks for the additional details Marlenio. Not immediately clear what's going on there, and we're about to release 2.3.2. In the interest of fixing this more common issue rather than the less common issue removing "set iface route default" fixed, I brought back 2.2.6 and prior behavior here for 2.3.2.

Thank you Chris,
tomorrow i install latest 2.3.2 build with fix.  :)

EDIT: test with 2.3.2 snapshot 20160715.0559. Works. :)
