system connection remove: use Args function to validate

Browse Source 
Using the ExactArgs(1) function is better because we have less
duplication of the error text and the ValidArgsFunction uses that to
suggest shell completion. The command before this commit would suggest
connection names even if there was already one arg on the cli set.

However because there is the --all option we still must exclude that
first.
