fix(database): schema/extension creation timestamp field values mismatch

[kon14]

This PR resolves the following Database timestamps (createdAt, updatedAt) issues:

1. SQL schema doc creation timestamp mismatch (create(), createMany())
2. SQL/Mongo adapter operations explicitly setting timestamp field values regardless of modelOptions.timestamp
3. Schema extension creation timestamps mismatch

In regards to [2]:
Sequelize completely ignored explicit query timestamp values.
Mongoose would use provided values, but doesn't really require setting them anyway.
