[Bug] fix pagination in jobs route

[merobi-hub]

Problem

Unlike in the case of datasets, for jobs, page navigation is displayed whether or not there are jobs/pages in the namespace. The page total advances while the total job count remains zero.

Solution

This hides pagination when there are no jobs.

One-line summary: hides job pagination in the case of no jobs.

Is this the same solution we use for datasets? Ideally, there would be a general purpose paging controller, but that is a bit out of scope here.

[merobi-hub]

@phixMe yes, this change refactors code that was basically the same as in datasets. Agree that a general purpose solution would be ideal. This will fix the pagination in the meantime.

Thanks @merobi-hub
