Problem during the plugin activation version 1.7.3

[verdanatech-emanoel]

Problem during the plugin installation. When trying to activate it, an issue occurs in the PluginSatisfactionSurvey class on line 97. Since this class extends CommonDBTM, the canCreateItem method must return a boolean value, just like in the parent class.

Sorry but https://github.com/pluginsGLPI/satisfaction/blob/master/src/Survey.php#L97 there is nothing
