this commit] `Subquery.as_sql(...)` method returns incorrect SQL removing
first and last symbols instead of absent breakets:
{{{
from django.db import connection
from apps.models import App
q = Subquery(App.objects.all())
print(str(q.query))
# Output SQL is valid:
# 'SELECT "apps_app"."id", "apps_app"."name" FROM "apps_app"'
print(q.as_sql(q.query.get_compiler('default'), connection))
# Outptut SQL is invalid (no S letter at the beggining and " symbol at the
end):
# ('(ELECT "apps_app"."id", "apps_app"."name" FROM "apps_app)', ())
}}}
