No files shown in Commit pane for the initial commit in SHA-256 repos

[kytta]

Describe the bug

I am using SHA-256 commit hashes on a repo (created with git init --object-format=sha256). In it, lazygit continues to work fine, but when I try to diff individual files of the initial commit, the window is empty.

To Reproduce

Steps to reproduce the behavior:

1. Create a SHA-256 repo with git init --object-format=sha256

2. Add and commit any file

3. Go to [4] Commits > select the commit > press Enter to enter diff view

4. No files are shown, as if the commit is empty

5. Add and commit another file

6. Go to [4] Commits > select the latest commit > press Enter to enter diff view

7. Everything is fine

8. Initial commit is still broken

Expected behavior

The committed files are shown

Screenshots

Commit list view: diff shows file in commit	pressed Enter: commit appears empty
