unknown shorthand flag -A in exo api

[pierre-emmanuelJ]

first:
unknown flag

go run main.go -A preprod api vm ls
unknown shorthand flag: 'A' in -A
exit status 1

and with long flag version

go run main.go --account preprod api vm ls
API error ParamError 431 (InvalidParameterValueException 4350): could not find account preprod in domain XXXX-xXXXXX-XXXX-XXXXX
exit status 1

but without api it's working good

go run main.go --account preprod vm ls
