Repair remove unit button

Repair remove unit button

Python and Go have differnt remove unit signatures, we 
called it in a loop with single names but the go env still
expected an array, not a string. This will conditionally
trigger the behavior based on env type.

LGTM

Thanks for this fix
(chunk missmatch so no notes)

Thanks for the review anyway. I think maybe a better plan is to put the
difference into the env object and not the calling code, but this was an urgent
bug and I'd like the fix landed even if we revisit it.
