Count trashed items in the storage count

- XXX count trashed items in the storage count <- prevent filling the recycle bin with data
- we don't count storage count in recycled, but should check if user has enough storage to restore. This is because we will prevent users to delete the content of their recycle bin themselves, and it will be removed by batch by a job.
- make sure the list of items (`getStorageFilesMetadata`) adds a trashed property, so the UI can prevent going to this item. Maybe the UI should allow to delete items on the spot.

This will add up to a lot of users their storage!!
