Enes Cakir 02c8a89c29 Switch TimestampMigrator from IntegerMigrator
IntegerMigrator doesn't allow duplicate migrations (1_foo, 1_bar).
Requires manual renaming for simultaneous migrations.

Here's comparison in detail:
https://sequel.jeremyevans.net/rdoc/files/doc/migration_rdoc.html#label-Two+separate+migrators

The TimestampMigrator will be used if any filename in the migrations
directory has a version greater than 20000101.

IntegerMigrator keeps version information at scheme_info table with an
integer. But TimestampMigrator keeps version information at
scheme_migrations tables with all filenames.

It's not backward compatible. You need to reset your database or create
and fill scheme_migrations table manually, then drop scheme_info table.
