Ambiguous option error should not appear if Arg is SUPPRESS

Due to backward compatibility there are arguments hidden.
For example:

--tenant-id and --tenant_id

On those case the abbreviation mechanism if a user enter
--tenant throw that there is an ambiguity but the helps only
show --tenant-id as an optional argument.
This change remove this ambiguity if one of them is hidden.
