[imp] A few more 2.3.7 queries

[Chuck Hagenbuch]

Quoting francus@metsny.yossi.com:

> In 2.3.6 the horde_prefs table was defined in imp/config/conf.php and
> allowed mysql as a parameter. It appears that in 2.3.7 it is defined
> in horde/config/horde.php and mysql is not an allowable parameter, only
> sql is. In any case preferences that were saved with 2.3.6 do not show
> up in 2.3.7 even though the name of the datbase in the relevant config
> files is horde_prefs under both versions.

Make sure that your table schema matches the one in horde/lib/Prefs/sql.php.
