The search widget wrappers for relations have two issues
* They recursively load whatever relations are defined. With self-referencing this leads to 💀
This is addressed by only loading one level of relations in search widgets.
* They would load even when hidden, leading to long load times on attribute table opening.
We now only actually load the form on the show event
