constructor() always gets all construction properties set,
at least to defaults (unless you call it manually).  If you
mean set to something else than the default, well, defaults
are supposed to be valid values.

Anyway, constructor() cannot fail AFAIK it would make
g_object_newv() crash.  However, it can construct an object
that is understood as invalid by your app.  So instead of
checking whehter the object was constructed you can check
whether it is valid.
