Modifying files from the iOS app doesn't create new versions on server

[StCyr]

Steps to reproduce

1. Modify a text file on the iOS app
2. Browse to the file in a web browser and look at its versions details

Expected behaviour

A new version of the file should have been made once the iOS client has sync'ed with the server

Actual behaviour

No new version is created

Reasoning or why should it be changed/implemented?
