heroku/heroku — Issue #228: show usage when running: heroku destroy appname

To destroy a particular application, it's:

`heroku destroy --app appname`

But if I type:

`heroku destroy appname`

It just tells me that I need to specify an appname. It should do this and also tell me I have invalid usage, like when doing `heroku config:add` with no arguments:

```
$ heroku config:add
Usage: heroku config:add = [= ...]
```

One situation in which it's a bit more confusing is running `heroku destroy appname` inside a directory that contains an app (for this example app2). In that case it asks to confirm destroying app in the current directory (app2) when the user's intent (which they expressed incorrectly) was to destroy app2. I suppose if the user was really distracted it could cause them to destroy the wrong app.
