Panic on request to unstage lines

[strandloper]

Any attempt to unstage one or more lines in a staged file results in an unexpected panic.

Steps to reproduce the behavior:

1. Stage a file with changes
2. Select one or more lines in a hunk in the staged file
3. Press s to unstage the lines
4. The following is displayed

GitUI was close due to an unexpected panic.
Please file an issue on https://github.com/extrawurst/gitui/issues with the following info:

PanicInfo { payload: Any { .. }, message: Some(index out of bounds: the len is 202 but the index is 202), location: Location { file: "asyncgit\\src\\sync\\staging\\mod.rs", line: 42, col: 25 }, can_unwind: true, force_no_backtrace: false }

I expected the selected lines to be removed from the hunk in the staged file and a new unstaged version of the file to be shown with a new hunk containing the lines I requested to unstage.
