Test extension xcode project

Using this _locales/en/messages.json:

{
    "hello": {
        "message": "Hello $1"
    }
}

I get this output in Safari's console when inspecting background page or service worker:

browser.i18n.getMessage("hello", "world") // "Hello world"
browser.i18n.getMessage("hello", "world $2") // "Hello world "
browser.i18n.getMessage("hello", ["world $2", "!"]) // "Hello world !"
browser.i18n.getMessage("hello", "$1") // ** never returns **

Firefox gives expected results:

browser.i18n.getMessage("hello", "world") // "Hello world"
browser.i18n.getMessage("hello", "world $2") // "Hello world $2"
browser.i18n.getMessage("hello", ["world $2", "!"]) // "Hello world $2"
browser.i18n.getMessage("hello", "$1") // "Hello $1"
