Decouple store creation from filesystem templates

[phlax]

We should use the templates/src language from the db.

The only implication of this is that it means that template/src langs must be created first (this may happen already)

@phlax are we reading the FS when we init a language? Even though we've loaded files in Templates lang? Ouch.

There are cases where you might not have a template language. So I'd say you must have a templates language first if you want the TP to be initialised from templates. But not having a template language shouldn't block creating a TP, as you might load it from external files without needing templates.

This is exactly the previous behavior.

Adding a new TP from the UI will benefit from this, since it already requires the templates files to exist on disk then creates new TP files on disk and then imports them to the DB.
