This reverts commit d31edc448cfc9b300b5e408d60e4c4ef6ff37028.

See the discussion in issue #149; this evaluated get_language
when the models were loaded rather than upon rendering the view

Closes #149

This potentially breaks what was achieved in !126. I gave it a superficial glance and it looked like the migration still works, but perhaps this could do with some more thorough checking.
