Partial fix for #711. Widget enable/disable fixed, but does not address widget show/hide

To include visibility fix, try adding:

 if (this.resizable === false && widget.state.visible === false) { classes.push('d-none') }

to ui/src/layouts/Group.vue at line 147 (inside getWidgetClass)

It is essentially stating: "If not wysiwyg editing (resizable false) and widget.state.visible is false, apply class d-hide"
d-hide remove the widget from webpage layout by setting display: none !important
