Regression in dokku enter command

[kminek]

Description of problem

I no longer can enter app container with following command (dokku v0.34.4)

dokku enter appname

It was possible in previous versions of dokku (like v0.32.3) without specyfying any optional arguments. I think it was "broken" with this change: 83b0cf4

Steps to reproduce

see description field

dokku report $APP_NAME
