Missing deleteWebhook method

[Pawilonek]

I found that removing the webhook URL from a bot was available (see: commit and #246) but later removed during some refactoring: commit. I tested this API call like this:

_, err = bot.MakeRequest("deleteWebhook", tgbotapi.Params{})

It still works fine and removed my webhook.

Is there any reason why this method is gone? Or, it was just a mistake? In the second case, I would be happy to make a PR with a fix.

will delete webhook as well:
w, err := tgbotapi.NewWebhook("")
if err != nil {
log.Fatal(err)
}
_, err = bot.Request(w)
if err != nil {
log.Fatal(err)
}
