java.lang.NumberFormatException should just result in http error code

I was testing some code I wrote to see how it would handle
error conditions and found this issue when trying to purposefully
add (POST) a bogus flow via the REST API.

In this case, I was trying to add a flow with switch ID 'G'.

1. note: python dictionary syntax
   newflow =
   Unknown macro: {u'actions'}

I saw expecting something like
Status: 500 Invalid Configuration (You're an idiot)
-or-
Status: 404 OF|00:00:00:00:00:00:00:0G : Node does not exist

I believe the GET function of the API does handle this correctly.

Here's the traceback result:
