Stashing deleted files reports error

[rjra100]

Issue Type: Bug

To reproduce:

• Open a git repo
• Delete a file
• Modify another file
• Stage either the deleted file alone, or both files (+ button in Source Control pane)
• Stash the staged changes

Expected:

• Staged change is stashed and restored, no error is reported.

Current behaviour:

• Changes are stashed, but "Unable to stash changes" warning pops up, and the staged changes are not restored. Output channel contains message along the lines of

[2022-07-13 08:15:26.038] Function._handleError
EntryNotFound (FileSystemError): Error: ENOENT: no such file or directory, stat '/workspaces/myws/path/to/deleted/file.xxx'

Note: This looks like https://github.com/gitkraken/vscode-gitlens/issues/1806, which was closed as no longer reproduceable. It appears that another file in the workspace must be modified to reproduce the issue - a deleted file alone does seem to stash OK.
