XliffTasks breaks with strongly generated resources classes

- [ ] This issue is causing unreasonable pain

Enabling generated strongly typed code for resources breaks XliffTasks with:

> error MSB3573: The language for a strongly typed resource class was specified, but more than one source file was passed in. Please pass in only one source file at a time if you want to generate strongly typed resource classes.
