This sequence has never been used. I manually bumped it twice when setting up the review.source.android.com site and then realized how useless it was, as I could have assigned the indexes 1 and 2 by hand when creating the site. Remove the sequence to clean up the schema. Change-Id: I0408b1ab25ce1b6e0816303aa363544876b541a2
