v4.5.0: Undo function makes sync experience suboptimal

[msrex]

when you upload a file and select to overwrite the existing file, it does not create a new version immediately, but creates temporarily for the undo functionality a file (2). If you wait for a while until you reload the page, that file is being synced to the desktop or displayed in the webfrontend or mobile app. Then, after you reload the page, this change is being reverted and a newer version of the original file is being created.
This is confusing.
I propose to change this to the immediate creation of a new version with a notice in the yellow pop-up at the top of the screen telling the user that a new version was created.

Reproduction:

1. create a file (e.g. hello) with the webfrontend
2. on the local desktop create a file with the same name but different content
3. upload the file via the upload in the webfrontend
4. DO NOT RELOAD THIS PAGE!
5. in a second browser or with the mobile client view the directory; or sync to your local desktop with the owncloud client

workaround will go live with OC5: undo will be removed

So there will be no undo at all?

We have a new trash app that replaces that feature

thank you!

It's more powerful and doesn't have the bug that is described here anymore :-)
