ve.dm.MWTemplateSpecModel: Account for data.maps being undefined

Browse source 
This new property is optional and should not be assumed to be present.
Follows-up 2ac7959849.

The constructor defaults 'maps' to an empty object, so there's no need
to add a "|| {}" in extend() or getMaps(). We merely need to make sure
we don't accidentally dereference the default in exchange for undefined.
