bug: renaming file by only changing the case results in file getting deleted

Steps to reproduce bug:

On Lubuntu 24.04 with Tixati v3.29, do the following:

Click a Name of an already completed torrent in your Transfers screen.
Click on the Files tab.

Right click a file and Rename the file but only change the case. (e.g. Change "INFO.nfo" to "info.nfo")

You will get popup that says the following:
New File Name Already Exists
Would you like to attempt to merge the files?

Click Yes

Wait for it to finish "Moving"

Force Check the torrent

Notice that the file was deleted and the status for the file will be:
error opening: No such file or directory (2)

That sounds more like an operating system bug, not a Tixati bug. Windows also has bugs when changing case only in a file name.

The bug no longer occurs with v3.31.
