When dropping a table, the table and its views are dropped
in parallel, this is not a problem as for itself but we
have mechanism to snapshot a deleted table before the
actual delete. When a secondary index is removed, in the
snapshot process it looks for it's schema for creating the
schema part of the snapshot but if the main table is already
gone it will not find it.
This commit serializes views and main table removals and
removes the views prior to the tables.
See discussion on #5713
