Missing dependency for DerivedProperty

[pixelzoom]

Discovered in https://github.com/phetsims/axon/issues/441 ...

In Spring, missing dependency on this.leftProperty:

    this.rightProperty = new DerivedProperty( [ this.equilibriumXProperty, this.displacementProperty ],
      ( equilibriumX, displacement ) => {
        const left = this.leftProperty.value;
        const right = equilibriumX + displacement;
        assert && assert( right - left > 0, `right must be > left, right=${right}, left=${left}` );
        return right;
      } );

In https://github.com/phetsims/hookes-law/commit/2d3c89dd1d19ccd5a3df7641d3ce260477dd6bbd, @samreid added accessNonDependencies: true to temporarily silence this problem.
