Return stub deployments when matching records do not exist.

The stub deployment is subsequently used to look-up the application by name.
This lets showLogs, configureApp, setProperty, and unsetProperty interact with
shinyapps.io when the client lacks a deployment record.

Does not address issues with publishing, such as #1013.

Fixes #985
Fixes #989
