Modify database-evolutions.txt to use the correct sequence list name
Review Request #3462 — Created Oct. 28, 2012 and submitted
According to http://django-evolution.googlecode.com/svn/trunk/docs/evolution.txt the list name should be SEQUENCE instead of SEQUENCES. Using SEQUENCES will cause the list to be ignored. Applied s/SEQUENCES/SEQUENCE to database-evolutions.txt.
