Invalid hint for unknown short argument available in other commands

[jrohel]

PR #1858 introduced a hint for an unknown argument available in other commands.

However, there is a problem with a group of several short arguments. For example:

# dnf -yl upgrade
Unknown argument "-yl" for command "dnf5". Add "--help" for more information about the arguments. 
The argument is available for commands: . (It has to be placed after the command.)

Instead of being told that the second argument 'l' is unknown (or in this case, that it is available for repoquery), the user is told the information for the first argument 'y', which is available globally (an empty command is displayed).
