Crash on save in /srv/ owned by root: runtime nil pointer dereference

[JonasAlonso]

When saving a file with Micro inside a folder under /srv/ (owned by root), Micro crashes with a nil pointer dereference. This is reproducible.

Steps to Reproduce:

1. Connect to a server via SSH (in my case with kitty terminal).
2. Create a folder under /srv/ (owned by root):

sudo mkdir -p /srv/conf.d
cd /srv/conf.d

3. Run micro and try to save a file.
4. Micro crashes with the following panic:

Micro encountered an error: runtime.errorString runtime error: invalid memory address or nil pointer dereference

Environment:

Micro version: 2.0.13
OS: Ubuntu 24.04 on Hetzner VPS (ARM64)
Terminal: Kitty over SSH

Notes:

Issue only happens in /srv/ (root-owned).
Crashes consistently when attempting to save.

Does it still happen in the latest (nightly) release? There have been some recent changes to the code related to saving with sudo so there's a chance this has already been fixed.

Fixed with #3082 in v2.0.14.
