Fix mojom Java generator running on its own.

Fix mojom Java generator running on its own.

It turns out that running self.GetStructs() not only gives you the
structs, but changes the state of the module, annotating structs with
necessary information.  Therefore we need to run .GetStructs() in the
Java generator as we do in the other generators.

This patch makes the java generation work on it's own, ie. with "-g
java".
