Removed old input checks on entity permission checkboxes

Old input check potentialy causing issues (#89) and is not needed on the pages which it shows.

 
 <label>
     <input value="true" id="{{$name}}[{{$role->id}}][{{$action}}]" type="checkbox" name="{{$name}}[{{$role->id}}][{{$action}}]"
-           @if(old($name .'.'.$role->id.'.'.$action) || (!old() && isset($model) && $model->hasRestriction($role->id, $action))) checked="checked" @endif
-    >
+           @if(isset($model) && $model->hasRestriction($role->id, $action)) checked="checked" @endif>
     {{ $label }}
