Review use of Property name as key

[KDederichs]

Description
Currently it seems like the Guessers are using the field name as key for some reason? That causes the console to be rightfully flooded with errors like this:

Warning: Encountered two children with the same key,.$redirectUrl. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.

so I'd suggest that's either removed where no key is necessary and replaced with the ID of the object where it is.
