Title: add start and end parent != undefined in d3_layout_bundlePath while

An undefined import causes a fatal error in the bundle-radial demo. This commit avoids the error, the ui will go on to draw a line to a blank node. To recreate initial undefined error add a un-"name"ed node to one of the imports in examples/data/flare-imports.

Thanks for sharing such an awesome tool.
