Describe the bug

When trying to access a URL through canvas.NewImageFromURI() in a test I am getting a panic.

This works fine in normal app code though.

    "fyne.io/fyne/v2/canvas"
    "fyne.io/fyne/v2/storage"
)

func TestImage(t *testing.T) {
    uri := "https://images.evetech.net/characters/93330670/portrait?size=64"
    u, err := storage.ParseURI(uri)
    if err != nil {
        panic(err)
    }

Additional Information

Andy mentioned on Discord that the cause might be that http/https is not mounted for storage in the test runner and suggested to open a bug report to change that.
