When testing force job updates on page views

Cirrus relies on delayed jobs and by default those are only checked every
5 minutes or so.  This checks them on every page view in the testing config.
This allows our tests to run much more quickly.

Also engages the experimental highlighter in testing.  Mostly because
to get this config working nicely in vagrant we use
Ib0ed378be272940d49e47a335e57123a1ecc6a78 which would undo that.
