Do not delete encrypted subfolders

[tobiasKaminsky]

• have /a/enc/ folder hierarchy, where "enc" is an encrypted subfolder
• if a client now deletes "a", "enc" is also deleted
• this is not wanted, and as long as we do not have trashbin support for e2e files, we should block this

--> when deleting "/a/" only files and folders that are not encrypted shall be deleted

We cannot do this on client side, as we only trigger "del /a/" via webdav

Can be a solution ...
EDIT: a little dirty but coherence

Hmm, I would disagree - if I delete the parent folder 'a' - regardless of subfolder type I'd want to delete all the contents.
