I did some tests, this are the results:

• creating a top-level folder, mark is as e2e, upload a file -> activity "you created a encrypted file" -> ✅
• create a sub folder in the e2e folder, upload a file to the subfolder-> activity view is broken (loads forever) 💥
  oc_activity entry looks like this:
  9|1519823263|30|file_created|admin|admin|files|created_self|[{"131":"\/E2e2\/Foo\/fa39a4b131a840d6a384ecf13eba1498"}]||[]|/E2e2/Foo/fa39a4b131a840d6a384ecf13eba1498|http://192.168.178.42/index.php/apps/files/?dir=/E2e2/Foo|files|131
• create a normal (unencrypted) folder, create a e2e sub-folder, upload a file -> activity "you created a encrypted file" -> ✅

Ah, failed on the recursion.

Rebased it, but only changed the last commit.

tested again. Everything seems to work now
