Overwriting populated folders using web ui leads to errors and unexpected behaviour.

[SergioBertolinSG]

Steps to reproduce

1. Upload a folder with 5 subfolders with some files inside each folder using web ui.
2. Upload again the same folder. When conflicts are detected say no.
3. Upload again the same folder.
4. Refresh the page.
5. Duplicate a file in one of the subfolders to upload.
6. Upload again the same folder.

Expected behaviour

The upload detects that it is an overwrite and asks if the folder should upload again the files.
Showing the conflicts.

Actual behaviour

The behaviour is erratic, sometimes the upload is just ignored, other it warns you with an upload cancelled warning. And others it simply fails this way:

I think this never worked properly...

@SergioBertolinSG not reproducible on master 7c7e4f9

It is likely that some other of my related PRs fixed it. Can you verify ?

[SergioBertolinSG]

Testing in current master, the step 2 simply doesn't happen. When uploading again the folder, it is not detected as an overwrite.

[PVince81]

In my test it worked. I dragged a folder from dolphin (file manager) into the current folder.

Did you drag onto a subfolder maybe ?

[SergioBertolinSG]

I do this (on current master):
