Plunkr Case (Bug Reports)
https://plnkr.co/edit/ffyN77iR3t3j4utIGfGh?p=preview

Current behavior
Specifying the prop maxlength of <Spinner /> will cause errors/crashes.

Expected behavior
Expected component not to crash and to update its value.

Minimal reproduction of the problem with instructions
Specify the maxlength prop of <Spinner /> and the component will no longer work.
The issue is happening because of the following line of code:

primereact/src/components/spinner/Spinner.js

Line 106 in e879098

if (this.props.maxlength !== null && this.value.toString().length > this.props.maxlength) {

this.value.toString() should be replaced by this.props.value.toString().
