Snippets are unreliable

**What did you expect to happen?**
When creating a snippet with `+snippets/new`, `yas-load-snippet-buffer-and-close` should guess something, but it always asks for the mode and folder instead.

**What actually happened?**
Snippet creation and loading is inconsistent.

**Additional details:**
- [Private config](https://github.com/mrbig033/doom2/blob/main/config.org)

I have updated this config to completely remove the `snippets` module. Yanisppet now works. [Open this commit](https://github.com/mrbig033/doom2/commit/7e53c61f71a1d5b13e9edd8833251a2daa8682dc) to see the exact settings in which the issue occurs.

**Steps to reproduce:**
1. Open any file
2. `C-c & C-n` or `M-x +snippets/new`
3. Create new snippet
4. Yasnippet should guess or remember mode
5. Add mode and folder manually
6. `yas-load-snippet-buffer-and-close`
7. Try expanding snippet
8. More than half the time, this doesn't work.

**-->** Sometimes, when trying to visit new snippets with `+snippets/edit`, I get this message: `or: Wrong type argument: yas--template, nil`. Calling `M-x yas-visit-snippet-file` directly does not give me this error. Binding a key to `yas-visit-snippet-file` ends up calling `+snippets/edit`.
