/object endpoint doesn't work with drop down profile

[edmondchuc]

For example:

http://localhost:5173/object?uri=https://draft.com/Australian-physiographic-units&_profile=prfl:dd&_mediatype=application/json

It just gives an error message in the UI as:

Not Found: This resource contains no links within Prez

but the browser fetches the data correctly over the network.

This relies on new behaviour in PR RDFLib/prez#155.
