el-patch-concat macro does not work in templates

Emacs version: 29.3
Emacs started as: emacs -Q
OS: Linux (NixOS)

How to reproduce:

(require 'el-patch)
(require 'el-patch-template)
(require 'nameless)

(el-patch-define-and-eval-template
 (define-minor-mode nameless-mode)
 (setq nameless-current-name
       (replace-regexp-in-string (el-patch-concat (el-patch-add "\\(°\\)?")
                                                  "\\(-mode\\)?\\(-tests?\\)?\\.[^.]*\\'")
                                 "" (lm-get-package-name))))

Eval output:

  funcall-interactively(eval-last-sexp nil)

(The el-patch-swap macro works as expected here.)

The el-patch-concat macro works just fine with el-patch-define-minor-mode in this case.

Let's start with adding a unit testing framework, that will help make it faster to fix these sorts of issues and ensure they stay fixed, so issue reports like this don't have to wait as long. I've started in #73 and will continue adding more until the problem is resolved.
