FindOne() does not honor multiple where()

**Node version**: v8.16.0
**Sails version** _(sails)_: 1.2.3
**ORM hook version** _(sails-hook-orm)_: 2.1.1
**Sockets hook version** _(sails-hook-sockets)_: 1.5.5
**Grunt hook version** _(sails-hook-grunt)_: 1.0.8
**DB adapter & version** _(e.g. sails-mysql@5.55.5)_: 1.0.2

I am in the process of migrating to version 1 and their is a breaking change that I did not see on the migration documents. This used to work in the prior version.

Agreement.findOne()
.where({id: agreementId})
.where({locationId: employee.currentLocation.id})

Now this fails with

More than one matching record found for `.findOne()`:

I stepped through the adapter code and it ignores all .where() except the last where, which is an issue.

Reproduce the chained Agreement.findOne().where({id: agreementId}).where({locationId: employee.currentLocation.id}) query using Node v8.16.0, Sails 1.2.3, sails-hook-orm 2.1.1, and the reported database adapter version. Start in the adapter code where the query criteria are assembled, as the report says only the last where is honored. Done means both predicates are applied and the multiple-match error no longer occurs when only one record satisfies them.
