[Bug Report] Renamed files/directories keep getting detected as duplicates repeatedly

[deliciousnights]

When renaming some of the already scanned files and re-scanning leads to the following log entries:

[2021-05-24 23:41:40] Y:\ph\thestartofus\thestartofus (20201202) [ph5fc7a8306a205].mp4 not found. Calculating oshash...
[2021-05-24 23:41:40] Y:\ph\thestartofus\thestartofus (20201202) [ph5fc7a8306a205].mp4 already exists. Duplicate of Y:\ph\thestartofus\THESTARTOFUS (20201202) [ph5fc7a8306a205].mp4

Looks like it happens only if the only change in the file name is a changed of a letter(s) case (upper/lower).
These messages do not go away with repeated scans.

To Reproduce
Steps to reproduce the behavior:

1. Have Stash scan a certain file
2. Rename the file, but only change a letter from uppercase to lowercase, or vice-versa
3. Scan the file again

Expected behavior
Stash should accept the new name and forget the old, non-existing one.

Stash Version: (from Settings -> About):
v0.7.0

Desktop (please complete the following information):

• OS: Windows 10
• Browser: Firefox

Stash relies on os.Stat for the duplicate checks. If os.Stat returns ok then that probably means that the filesystem is case insensitive? Can you check what filesystem is used in the Y: drive ?

Confirmed on Windows local drive.

Filesystem is NTFS on windows - case insensitive.
