v3.31.0 introduces bug

The following code works fine in v3.30.0:

const query = {
    where: {
        or: [
            { username: username },
            { email: username }
        ]
    }
};
self.userModel.findOne(query, function (err, user) {

As of v.3.31.0, I get the following error:

Error: The where clause "abc@xyz.com" is not an object

Looks like something broke in the _coerce function.

Comienza en lib/model-utils.js, en las llamadas a _coerce alrededor de las líneas 369, 394 y 552, y luego sigue la normalización desde lib/model-utils.js hasta findOne en lib/dao.js. Reproduce lo proporcionado o la consulta en v3.31.0 y compárala con v3.30.0. Se considera terminado cuando la consulta acepta la misma forma de objeto sin informar del valor de email como no objeto.
