Call scoped_refptr<T>::get() rather than relying on implicit "operator T*"

This upates calls to bound temporary objects to also use get().
While it has the same semantic equivalence to the existing code, this generally
represents a dangerous pattern - indeed, part of the whole motivation for this
change is to make this anti-pattern very visible to authors.

This change simply updates all of the call sites, to allow the "operator T*"
to be removed and preventing new instances. The existing instances will then be
reviewed for "suspicious" changes and updated to use/pass scoped_refptr<T>
rather than T*, as appropriate.
