This patch ( https://reviews.mahara.org/#/c/5784/3 ) fixes institution blog pagination. But! When you first go to the Administration -> Institutions -> Journals, pagination is still broken. This is because on first loading the page, we have the query param "institution=1". The artefact/blog/index.php page passes this to institution_selector_for_page(), which understands "1" to mean "show me the default first institution".

But, the paginator JS automatically also takes this "1" from the query and passes it to the paginator script artefact/blog/index.json.php. And that script doesn't know what to do with it, so it crashes.
