How to reproduce

• Leaflet version I'm using: 1.0.3
• Browser (with version) I'm using: Chrome 57
• OS/Platform (with version) I'm using: OS X 10.11

1. Create L.Polyline with empty latlngs
2. Add that layer to an L.Map with preferCanvas: true

What behaviour I'm expecting and which behaviour I'm seeing

Nothing should be displayed, but it should run without console errors.
