config: fix find_handler logic

Without this change, the handlers listed in the config_handlers or
command_handlers arrays (depending on reading or active) in commands.c
would be valid subcommands. To make matters worse, they would also take
precedence over the defined subcommand handlers.

This corrects find_handler to only work on the handler array given
instead of implicitly trying others.
