Updating publisher's dApps is not working

[dbadol]

Summary
The dApp "update" process does not work in the Windows desktop wallet v7.5. The workaround seems to be to remove the dApp completely and then publish it again.

Bug description
When in the Publisher section, clicking on a dApp proposes updating it. However, that doesn't work. It gives the following error message:

And in the logs: checkDAppNewVersion: Guid doesn't match, it's different DApps.

After trying multiple times, either with the "load" button or with drag-and-droping the file, it might accept it (for reasons unclear) and move to the next step:

But then, it gives the following error message:

And in the logs: Failed to publish app, {"error": "the dapp exists"}

Workaround
The only way to update the dApp is then to remove it completely, and then publish it again (which implies the payment of two transactions, instead of one).
