Intercept the module root to patch `transaction`

This commit intercepts the module root to patch the `transaction`
method.  This works because the `knex` module exports a
constructor and the object that the constructor constructs has a
`client` property that is the client being used.  This client
can have its `transaction` method updated in a way to preserve
context.
