mu4e: exiting a message shows the main view instead of the headers view

### I confirm that...

- [x] I have searched the [issue tracker](https://github.com/doomemacs/doomemacs/issues), [documentation](https://docs.doomemacs.org), [FAQ](https://docs.doomemacs.org/-/faq), [Discourse](https://discourse.doomemacs.org), and [Google](https://google.com), in case this issue has already been reported/resolved.

- [x] I have read "[How to Debug Issues](https://doomemacs.org/d/how2debug)", and will use it to provide as much information about this issue as possible.

- [x] The issue can be reproduced on the **latest** available commit of Doom.

- [x] The issue can be reproduced on a stable release of Emacs, such as 27, 28, or 29. *(Unstable versions end in .50, .60, or .9x)*

### Expected behavior

Upon setting `(setq mu4e-split-view 'single-window)` or `(setq mu4e-split-view nil)`, when I quit the message view I expect to be returned to the headers view. This is the behaviour I get when using

```
(use-package mu4e
:commands mu4e mu4e-compose-new
)
```

instead of the doom mu4e module.

### Current behavior

When I quit the message view I'm returned to the main view. There are no warnings or errors. Loading the package without doom's module doesn't exhibit this behaviour.

### Steps to reproduce

1. Open Emacs
2. M-x mu4e
3. M-: (setq mu4e-split-view 'single-window)
4. Open a headers view, such as a folder
5. Open a message
6. press q
7. be returned to main view
