In the site definitions TemplateAvailablility, the id value is completly ignored.
the bean does not contain any if value it could operate upon.

The class
info.magnolia.module.templatingkit.sites.TemplateConfig
does not contain an id variable and their according population.
Therefor the info.magnolia.module.templatingkit.sites.TemplateAvailability can not operate on the id value, but operates wrongly on the tempate name.

That would mean, that only one template with the same name can be provided, firs found first served.
