I've been trying to run tests/run_vagrant and it's builds and starts beautifully but while running the actual tests it tends to time out. At first I thought I had missed some DNS configuration but after some probing from @asm89 on IRC I found that when it gets to this line in ./test_deploy it seems like dokku url never exits:

URL=$(ssh dokku@$TARGET url $REPO)$FORWARDED_PORT

And I can confirm that when running it separately either like this (without an app name):

ssh dokku@dokku.me url

where with ssh -v the last line is:

debug1: Sending command: url

or like this (with a valid app name):

ssh dokku@dokku.me url test-nodejs-express-22080

it will never exit, or time out after like 5 minutes or something. The difference is that the one with a valid app name outputs the url as expected.

But running it like this (with an non-existent app-name) it exists properly with an error:

ssh dokku@dokku.me url foo

I'm thinking maybe it's really and issue in pluginhook and related to the comments in #236 but since it's easy to reproduce I figured it can be a separate issue.
