Institution blog pagination broken when you first visit the Institution Journals page

[Aaron Wells]

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 and says "A required parameter is missing or malformed The 'institution' parameter is not alphabetical only".

To replicate:

1. Install Mahara
2. Create a new institution
3. Go to Administration -> Institutions -> Journals
4. Create more than 10 journals for your new institution
5. Again click the "Administration -> Institution -> Journals" link in the menu (so that you again get the starting "institution=1" URL)
6. Try to use pagination to see the rest of your journals

Expected result: You paginate to the second page of journals for the institution
Actual result: Pagination fails, and you see an error message about institution not being entirely alphabetic

This probably got overlooked during testing, because if you have just created a journal in an institution, then you get returned to the Journals page with the institution's name in the URL. It's only when you click the "Administration -> Institution -> Journals" link that you see the "1" in the URL.

Medium priority, because you have to be using institution journals, and have more than 10 of them, for this to be an issue. Not 10 institution journal entries, but 10 institution *journals*. Probably a relatively rare use-case.

Also, there is a workaround. Create a second institution, and then after you're on the Institution Journals page, use the institution menu to go to the second institution, then back to the first institution. This will prime the URL with the institution's real name instead of "1".

The patch can break things if there are no institutions yet created and you try and go to the Institution -> Journals page.

I've updated the patch to deal with that issue
