Cole Miller 652f1fa3b0 git: Fix a race that caused incorrect hunk staging information (#53929)
In `GitStore::open_diff_internal`, when opening a `DiffKind::Unstaged`
diff, we previously always overwrote the `unstaged_diff` field of
`BufferGitState`. This causes a bug in the following situation:

- We call `open_unstaged_diff`, and it hits an await point where it is
loading the index text
- While that task is suspended, we call `open_uncommitted_diff`. It
reaches `open_diff_internal` and sets
`buffer_git_state.uncommitted_diff` and
`buffer_git_state.unstaged_diff`. It also sets the secondary diff for
the uncommitted diff to be the unstaged diff that it just opened.
- The `open_unstaged_diff` task wakes up and enters
`open_diff_internal`. It creates a new entity for the unstaged diff and
overwrites `buffer_git_state.unstaged_diff` with it, but it doesn't
update the secondary diff of the uncommitted diff, which still has the
entity that was produced in the previous step.
- Now the uncommitted diff's secondary diff will never receive updates
from the `GitStore`, causing staging information to be incorrect.

The fix is for `open_diff_internal` to not overwrite an existing
unstaged diff.

Self-Review Checklist:

- [x] I've reviewed my own diff for quality, security, and reliability
- [x] Unsafe blocks (if any) have justifying comments
- [x] The content is consistent with the [UI/UX
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)
- [x] Tests cover the new/changed behavior
- [x] Performance impact has been considered and is acceptable

Release Notes:

- Fixed a bug that could cause diff hunks to have an incorrect staged
status.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
