Correct return value of path_for

[hlcfan]

Method ViewPathBuilder#path_for is actually returning correct url or exception error message.

It's nil in the documentation, guess people forgot this when working on #1402. Correcting now.

Is that the correct message? I wouldn't expect it to look like an error...

TIL, take out the <,'> and it'll be all good then
