GVariant parser: fix tuple type checking

Browse Source 
Robert Ancell discovered that the GVariant parser messes up pretty badly
when the type of a tuple is specified and the tuple in the text being
parsed has a different number of elements (but otherwise matching child
types).

Check that we have the expected number of elements.

Closes #644786.
