[FIX] web: client action change password

1. To change the page title, you now have to call
`set_title` from `require('web.web_client')`

2. Without the `type="button"`, the `Change Password`
button is regarded as a `type="submit"`, therefore
submitting the form, on `web` on click,
and `web` doesn't expect this POST request.
The POST request must be done on
`/web/session/change_password` only.
