[Bug] Error on config reload

### Thank you for the bug report - [x] I am using the latest version of `doom-modeline` related packages. - [x] I checked [FAQ](https://github.com/seagle0128/doom-modeline#faq). - [ ] You may also try reproduce the issue using clean environment and minimal configurations with the command `emacs -Q`. ### Bug description When I reload my config with `SPC h r r`, I get the error `(wrong-type-argument stringp nil)`, seemingly triggered by `(setq doom-modeline-icon nil)`, except that I get the same error if I use `(setq doom-modeline-icon t)`. I do not get this error when Emacs starts; only when I reload the config. ### Steps to reproduce Put the following lines in `config.el`: ``` (setq doom-modeline-height 36) (setq doom-modeline-icon nil) (setq doom-modeline-enable-word-count t) (setq doom-modeline-continuous-word-count-modes '(markdown-mode gfm-mode org-mode text-mode)) ``` Restart Emacs and run `SPC h r r`. ### Expected behavior I should not get an error upon running `SPC h r r`. ### OS MacOS ### Emacs Version 30 ### Emacs Configurations Doom Emacs ### Error callstack ```emacs-lisp Debugger entered--Lisp error: (wrong-type-argument stringp nil) doom-modeline-update-battery-status() #f(compiled-function (sym val op where) #<bytecode -0x11199c4cffa3f53a>)(doom-modeline-icon nil set nil) (setq doom-modeline-icon nil) load-with-code-conversion("/Users/sivakalyan/.doom.d/config.el" "/Users/sivakalyan/.doom.d/config.el" t t) load("/Users/sivakalyan/.doom.d/config" t nomessage) (condition-case e (load path noerror 'nomessage) ((debug doom-error) (signal (car e) (cdr e))) ((debug error) (setq path (locate-file path load-path (get-load-suffixes))) (if (not (and path (featurep 'doom))) (signal (car e) (cdr e)) (cl-loop for (err . dir) in (list (cons 'doom-cli-error (expand-file-name "cli" doom-core-dir)) (cons 'doom-core-error doom-core-dir) (cons 'doom-user-error doom-user-dir) (cons 'doom-profile-error doom-profile-dir) (cons 'doom-module-error doom-modules-dir)) if (file-in-directory-p path dir) do (signal err (list (file-relative-name path (expand-file-name "../" dir)) e)))))) doom-load("/Users/sivakalyan/.doom.d/config" t) (let ((doom-module-context (let ((key '(:user))) (if key (doom-module-context key) (let ((index nil) (key nil) (path nil) (flags nil) (features nil)) (record 'doom-module-context index key path flags features)))))) (if (and (not doom-inhibit-log) (or (not noninteractive) (<= 2 doom-log-level))) (progn (doom--log 2 ":context:module: =%s" doom-module-context))) (doom-load (file-name-concat doom-user-dir "config") t)) (let ((doom-context doom-context)) (doom-context-push 'config) (doom-run-hooks 'doom-before-modules-config-hook) (let ((doom-module-context ...))
