Tags under institutions cause error

[Robert Lyon]

We now have a system where we can use special 'Institution tags' but we also allow institution admins to tag things in the normal was as well. The following case causes the error:

[WAR] 9e (lib/form/elements/tags.php:100) Trying to get property of non-object
Call stack (most recent first):

    log_message("Trying to get property of non-object", 8, true, true, "/home/robertl/code/mahara-testing/mahara/htdocs/li...", 100) at /home/robertl/code/mahara-testing/mahara/htdocs/lib/errors.php:520
    error(8, "Trying to get property of non-object", "/home/robertl/code/mahara-testing/mahara/htdocs/li...", 100, array(size 3)) at /home/robertl/code/mahara-testing/mahara/htdocs/lib/form/elements/tags.php:100
    display_tag("fats", array(size 2)) at /home/robertl/code/mahara-testing/mahara/htdocs/artefact/file/lib.php:729
    ArtefactTypeFileBase::get_my_files_data(0null, null, "insttwo", null) at /home/robertl/code/mahara-testing/mahara/htdocs/lib/form/elements/filebrowser.php:164

Steps to reproduce:

1) Have a site with an institution (Institution A) that contains 2 institution admins
2) Institution admin A logs in and uploads a file to the Admin -> Institution -> Files section
3) They then edit the file metadata and add a tag 'Cats'
4) They log out
5) Institution admin B logs in and goes to the Admin -> Institution -> Files section

They see the error

6) They then edit the file metadata and instead of seeing 'Cats' they see 'null'

Bug 1826788: Allow tags on institutions / group items still show

When tags on an artefact / view / collection / blocktype not owned
by a user, but rather a group or institution we should still display
it for a user who belongs to that group / institution
