What steps will reproduce the problem? 1. Update schema_info verison number after each step in migration

What is the expected output? What do you see instead? In a 10 step migration if #5 fails the schema_info version column will reflect that you are at version 1 when in reality version 4 has been executed with success.

Fixed.

The migration logic has been redone so that the schema version is updated after each successful migration execution.
