fix: templates loading reset

This fix the order ready method of eox_nelp works. Mainly this avoid
that if eox_nelp is intalled before eox_theming. eox_theming should not reset look_ups in it ready method.
https://github.com/eduNEXT/eox-theming/blob/v8.1.0/eox_theming/apps.py#L58

So with this change eox_nelp exteding template in the ready method would work.
