`syscall.Errno bad file descriptor`

**Describe the bug**
lazygit dies with the following:

```
2022/01/29 13:45:11 An error occurred! Please create an issue at: https://github.com/jesseduffield/lazygit/issues

syscall.Errno bad file descriptor
github.com/jesseduffield/lazygit/main.go:145 (0x555f4d362cb9)
runtime/proc.go:255 (0x555f4cdec107)
runtime/asm_amd64.s:1581 (0x555f4ce1a181)
```

**To Reproduce**
It happened 3 times across the last couple of days, but I couldn't recreate it on purpose so far.

The last time it happened I was just switching tabs - from 3 to 4, I think. Nothing special. I think I just completed a rebase before.

Some jest tests were running at the same time and there was a snapshot updated at the same time. Might be related. Might be not. Can't remember whether that was the case before, too.

**Expected behavior**
Don't die, lazygit!

**Additional context**
Lazygit is great. Thanks a lot!
