Cryptic python exception is shown when node.js binary isn't found #75

A recent Ubuntu upgrade recently renamed /usr/bin/node to /usr/bin/nodejs for me, which resulted in the following exception thrown whenever a javascript buffer loses focus:

Error detected while processing BufLeave Auto commands for "<buffer=1>":
Traceback (most recent call last):

This happens, for instance, on :bdel or on :help. It could be a bit more user-friendly if it mentioned which specific executable was missing.
