add app --dry-run breaks add app by creating the deploy key

[sympatheticmoose]

Describe the bug
If you run add app twice, first with the dry-run flag to see what should happen, a deploy key will be added to the cluster and then the second add will fail as unable to store secret with the same name.

What is the severity of the bug
Setting as minor for now given expected usage of dry-run... may raise to major.
