Merge indexes for reblog on statuses table (#5831)
We added an index for `[account_id, reblog_of_id]`, but we already have a similar index for `reblog_of_id`. Those index will be bigger according to statuses count. For example, `reblog_of_id` index uses 800MB for 10GB statuses table. So this patch swaps indexed columns like `[reblog_of_id, account_id]`, then it will covers both usage with single index. Since those index creation may take a while, I've also disabled previous index creation.
