a11y: Only allow get_name/description when realized

These functions rely on self->accessible_role
being set, and that is only the case for realized
contexts.

In practice, this is not a problem. Contexts are
realized before ATs can get their names or descriptions,
and the inspector realizes contexts too, nowadays.

The only place where this caused a hickup is the
testsuite.
