Syncing two roots with the same folder name gets Drive into trouble

In web ui

• Create a folder specifications, subscribe to it with Drive
• Add some content to it

==> Observe that the folder and its content are synced properly.

• Create a sibling folder also with the title "specifications", from Web UI
• Add some content to it
• subscribe to it with Drive

==> Observe that Drive starts syncing but then stops, but we have one one specification folder, and the icon of the specification folder remain in "syncing" state

*Expected behaviour *
Synchronisation error, that says "Specifications folder could not be added as sync root because a folder with the same name already exists in there". All status icons are in a consistent state.

or, better:

Future improvement:
The second specification folder is locally renamed specifications_1 to avoid conflict, but this rename doesn't impact server rename. That way content is sync, we have no error and it is all good.
