Once you prove that this works, NEWS and test, please.

I think this is best done with a helper function and two invocations of that test function -- that will help us understand which condition is failing. Something like:

confirm_existing_application_use <- function(server) {
    # innards of loop
}
test_that("can find existing application on server & use it", {
  confirm_existing_application_use("example.com")
})
test_that("can find existing application on shinyapps.io & use it", {
  confirm_existing_application_use("shinyapps.io")
})

@hadley - do you have different recommendations?

This tests out properly for me. Running interactively I am prompted whether to redeploy to the application that was found, running noninteractively it assumes that's what I want, which is consistent with prior behavior.
