upgrade: duplicate messages for checkouts not being locked #2466
Description
I just noticed this oddity when running upgrade on a repo with a checkout:
rebar3 upgrade
===> Verifying dependencies...
===> App chatterbox is a checkout dependency and cannot be locked.
===> No upgrade needed for acceptor_pool
===> No upgrade needed for ctx
===> No upgrade needed for gproc
===> No upgrade needed for hpack
===> App chatterbox is a checkout dependency and cannot be locked.
===> App chatterbox is a checkout dependency and cannot be locked.
It prints 3 times that it can't lock chatterbox. Obviously it should only be once. It isn't a big deal but I figure finding out why it is hitting that 3 times could uncover some unnecessary processing going on, and it would at least make the output nicer.
