Avoid showing standard command not found message when possible

Browse source 
In bash, command-not-found handler causes the standard messages to
not appear. Because of events model in fish, it isn't really an
option, so I moved the standard command not found message to
fish function. This way, the messages aren't repeated, and the
standard command not found message appears only when handler
couldn't be found.
