Avoid creating a collection on Kobo device

[NicolaSmaniotto]

Is your feature request related to a problem? Please describe.
The calibre-web sync created a single collection (named "nicola", like the shelf). Is it needed by the device in some way for the sync?

Describe the solution you'd like
I'd like to remove/hide that collection at least from the home screen.

Describe alternatives you've considered
None.

Additional context
Not really a problem, I just don't use the collections on my kobo (I prefer to organize by series). That single collection is now always shown in the device home screen, in the second row. Before the sync the device suggested other books in the series or by the same author I was reading, which I find more useful than a single huge list of half the available books.
