Application singleton is not really a singleton. #1653

It seems that the application singleton is not really a singleton, or something weird happens with my app.

If you take a look at:
Screenshot 2019-04-19 20 18 21
you will see how some of my routes are registered twice.
I have a hunch this happens because in my app, i am also running a udp server, and inside it i defined a logger function like:

func logger() buffalo.Logger {
	return actions.App().Options.Logger

And i guess this somehow affects what's going on. It's just a hunch though.

However, if instead of:

    func App() *buffalo.App {
        if app == nil { ... }

i'm using sync.Once:

    var appOnce sync.Once
    func App() *buffalo.App {
        appOnce.Do(func() {  ...  })

Then my issue goes away, no more duplicate routes.

Steps to Reproduce the Problem

See above.

Expected Behavior

I expect to see unique routes.

Actual Behavior

I see duplicate routes
