helper/command: print the command output in case of error 

In case of error, a command should use command_print() to report
the error message, so it get printed only on the session that run
the command itself, and the message can be intercepted with the
tcl command catch if it has to be handled differently.
Current code drops the command output when the command returns
error, claiming that it's the command that *should* have printed
it already. This is true only if we *abuse* of the LOG functions,
but accepting the side issue of having the LOG printed in every
session and being unable to catch{} the error message.

Since we have switched to command_print(), change the code to
propagate the command output also in case of error.
