Bug 13149: Fix sequence of fields in sysprefs.sql

Bug 13149: Fix sequence of fields in sysprefs.sql

The sequence of fields in the SQL statement didn't
match correctly.

Test plan:
- Run the web installer on an empty database
- Make sure no SQL errors are shown
- Check the systempreferences table in your database,
  especially all UsageStats*
- Make sure the explanations are in explanation etc.

Alternatively:
- Save your database
- truncate systempreferences;
- Load the sql file sysprefs.sql
- Verfiy as above

Tested creating new database, then loading kohastructure and sysprefs.sql
Without patch sysprefs fails to load, with patch loads Ok!
No koha-qa errors
