`SearchVector` was changed in Django 2.2 to allow querying non-text fields
(#29582) by using `CONCAT` which automatically cast such fields to text
and deals with `NULL` value appropriately.
This had the unintended side effect of making the generated SQL loose it's
`IMMUTABLE` status as `CONCAT` can generate locale/TZ dependant output
which makes the generated SQL expression impossible to index against.
