If the update was a success, then that update message is also printed in
cmd/version.go

In general the code in internal should not print to the console.
However, since execution stops there if the update was not a success,
the output is moved into that if-condition to keep showing the error
message to the user before the program exits.

Has not been fully tested yet, as there is no real release to grab
at this point.
However, this also doesn't alter the default current behaviour,
so should be safe to merge anyway..
