refs #409
Count on :all rather than nil by default

fixes #409
Makes sure we use the params from the templates and merge them with the given params if given when creating a #link_to_next_page, #link_to_previous_page or #rel_next_prev_link_tags. This makes it consistent with the implementation in Kaminari::Helpers::Tag#page_url_for
add more specs to check if template params are used
