Gz fuel server allows models with duplicate author and name

[luca-della-vedova]

It seems two models with exactly the same name and author made it into the gazebo app portal:

Clicking each of them points to the same page https://app.gazebosim.org/anni/models/ur5_rg2.

This is causing a fair bit of issue in the Open-RMF side of things where we use model names to build a cache of fuel models and I believe it is probably not indended behavior?

@luca-della-vedova can you verify if this is still a problem. There was a caching issue on the Fuel server that was resolved last week which might have also fixed this. The URL for the ur5 model in the description no longer works for example.

However, I do see that the model count is 2 when searching for ur5 even though there's only one model shown

[luca-della-vedova]

The way I'm using to verify the issue is to look at the models page, since the model has been uploaded fairly recently it appears in the page as one of the latest ones:

Edit: Since the endpoint we are using in RMF is the one to list all the models I wonder if the behavior of this page is different from the searching that you tried?

It looks like listing the model of just that owner shows there's one model, but if I list all models, it shows two ur5_rg2 models owned by anni.
