Bug: "No link found for page" raised - apparently unnecessary

[mirko]

Hello,

I'm separating pages by years, so I set the currentYeare.g. to '2019'.
Backbone-paginator immediately raises a "No link found for page 2019"-error.
The Link-header field is set to </json/items?page=2018>; rel=prev.
The exception is raised in l608 (v2.0.8), because there's no link for the current (=2019) page(?)
It doesn't make sense to me and it works perfectly fine removing the exception.
