Mutation of static backend prop on Model

[diffcunha]

I found that if we set backend on a Model and then start a session with schema.withMutations(...) (for bootstrap for instance) this will change the static backend prop setting withMutations to true. From this point on every time we make a change we are literally mutating the store.

The bug is in Model.js file

// Model.js
static getBackend() {
    if (!this._sessionData.backend) {
        const BackendClass = this.getBackendClass();
        const opts = this._getBackendOpts();

        if (this.session && this.session.withMutations) {
            // HERE! This will mutate the static prop `backend` on the Model
            opts.withMutations = true; 
        }

        // ...
    }
    return this._sessionData.backend;
}
