Neogit starts producing errors when calling `neogit.open` twice from different `pwd`, OR when using a zsh terminal that runs the `powerlevel10k` theme

[tvsfx]

Description

I start getting errors in the following cases:

• I open the Neogit status buffer when it is already open, using the neogit.open command twice, when the cwd is not inside the project that my buffer is in
• I open the neogit status buffer for a specific project, and then open a zsh+powerleve10k terminal under a different cwd,

Neovim version

v0.10.0 (Neogit: 11dea1b )

Operating system and version

Ubuntu 20.04

Steps to reproduce

Self-variant

1. From $HOME, run nvim -u minimal.lua
2. Navigate to a random file, let's say random, in a random git repo without changing pwd (e.g. :e <path-to-random>)
3. Type \gs (keybind defined below) to call Neogit status for the repo containing the current file's folder.
4. Click back on tab that contains random
5. Repeat step 3
6. Error occurs

Shell variant (requires zsh/powerlevel10k) <Repeat steps 1-4 above>

5. open a terminal under the new CWD using :edit term://%:p:h//zsh
6. Error occurs

Expected behavior

No response

Actual behavior

The error trace is as follows:

E5108: Error executing lua: ...nkering/.min/plugins/plenary/lua/plenary/async/async.lua:18: The coroutine failed with this message: ...nkering/.min/plugins/plenary/lua/plenary/async/async.lua:18: The coroutine failed with this message: ...nkering/.min/plugins/plenary/lua/plenary/async/async.lua:18: The coroutine failed with this message: ...ing/.min/plugins/neogit/lua/neogit/lib/git/sequencer.lua:50: attempt to index local 'HEAD_oid' (a nil value)

Tested using minimal.lua, and I still get the error. For the shell variant; I do not get the error when I switch to bash or when I turn my zsh theme off. I assume this has to do with the fact that powershell10k has its own git status overview, which somehow interferes with neogit.
