Unable to delete project (if emails have not yet allowed for project?)

[einars]

Probably the issue with garden itself, not the cli tools, yet I don't see where to report that, so here it goes,

Running a test deploy (calendula), toying with it and then trying to clean it up, the garden falls over with the error, possibly due to ignored "allow emails from $app?" message,

$ garden delete eijeijei
