API: Folders created at level 0 instead of correct level

[jjlimepoint]

To reproduce:

http://[teampass-server]/teampass/api/index.php/add/folder/ZWxlcGhhbnQ7MDswOzA7MAo=?apikey=[omitted]

Expected: Folder created at level #1
Actual: Folder created at level #0. All root folders behave like children of it, at this point, so if you delete it, everything is deleted! - this is the same behaviour as #1764

Mitigation: If you log in as a user to the web ui, and select folders, it DOES get resolved, and then behaves correctly. Of course that's no good in a script - I couldn't find any API way to poke it in a way that causes that update to happen....

(Note: this also happens with folders that are children of non-root - exactly the same unfortunate behaviour :( )
