[1.9.x] Fixed #25510 -- Allowed runserver to start with incorrect INSTALLED_APPS. 

In that case, the content of INSTALLED_APPS will be ignored until it's
fixed and the autoreloader kicks in. I confirmed this behavior manually.
As explained on the ticket it's hard to write a test for this case.

Backport of df0a446fd4 from master

This regression appeared in 1.8.5 as a side effect of fixing :ticket:`24704`
