Comment (by kenial):

 If we're going with the hook, it still does "migrate" stuff in context of
 another application (in this case, gis). So hook isn't looking good. (is
 there a way to completely split into migrate and gis context in app
 initialization?)

 pre-migrate signal seems to be nice, but I find out ... it's `model`
 based. We're doing this on database-level. Maybe it's safe to be executed
 repeatedly, because when migrating only.

 My original approach was to add a method for this purpose (name was
 `before_migration`) to BaseDatabaseWrapper with empty implementation, and
 call it when running `migrate` command. For sure,
 `django.contrib.gis.db.backends.spatialite.base.DatabaseWrapper`
 implements this `before_migration` method to init metadata table.
