Add @AfterInject annotation support for Declex Model Classes (@Model)

[z3phyro]

I can't manage to use a @Bean inside a model because I can't make a method that get executed after the injection happens

The issue is not related with the models, it works fine for the models when they are injected, as well when they are injected from the DataBase, the issue is related to don't running the injections when the @UseModel annotated class is injected from within a @ServerModel request.
