b.Config.Storage.Get() for BoltDB does not return error if url is not found

[osalzgeber]

It seems that
*func (p Provider) Get(alias string) (string, error)
in storage/bolt/main.go
does not return an error if the url is not found in the boltdb.

The function just returns an empty url which results in always redirecting to the main page or a different page if root-redirect is enabled instead of resulting in a 404.

Possible fix would be to check the url:
if url == nil { return "", storage.ErrNotFound }
