how to activate web-mode for template

Hi,

I've read that mixing web-mode with vue-mode brings unsolved issues, but I've been using web-mode so much (and still continues on non vue projects) that using something different is painful.

So I thought I'd nevertheless try to mix them and see if the benefits of vue-mode would outweight the cons of the issues.

I tried to activate web-mode using this configuration

```elisp
(use-package vue-mode
:config
(add-to-list 'vue-modes '(:type template :name nil :mode web-mode))
(add-to-list 'vue-modes '(:type template :name html :mode web-mode)))
```

in a .vue SFC file, I then have vue-modes' value being

```
vue-modes is a variable defined in vue-mode.el.

Value
((:type template :name html :mode web-mode)
(:type template :name nil :mode web-mode)
(:type template :name nil :mode vue-html-mode)
(:type template :name html :mode vue-html-mode)
(:type template :name jade :mode jade-mode)
...
```

According to this [SE answer](https://emacs.stackexchange.com/questions/3397/how-to-replace-an-element-of-an-alist), I understand the elements I've added at the top of the list would override the default ones.

But when opening a .vue file, the active mode inside a `` section is

```
vue[vue-html] mode defined in ‘vue-html-mode.el’:
Major mode for Vue.js templates.
```

Any idea of what is wrong here ?
