In WP_Query::get_queried_object(), avoid PHP notices when is_tax is paired with an empty tax_query.

Browse Source 
It's possible to have an empty `tax_query` and `is_tax=true` when the initial
query contains a taxonomy var (and is processed as such during
`WP_Query::parse_query()`) but the taxonomy var is unset during a 'parse_query'
callback. While this kind of behavior is not necessarily something we need to
support, we should continue to avoid PHP notices in such cases, as we did prior
to WP 4.1.

Fixes #31246.
