Bug 1588613: Later session start so we can use DB config table

The session init code relies on $CFG->session_timeout, which is
normally defined in the config table. So, we need to start the
session after opening the database connection.

(In the event that there's an earlier session start, for instance
due to an error message, this will cause the session for that
page load to disregard any database config values. But that's not
a show-stopper, and there's no easy way to fix it.)
