Error logging improvement when the dev forget to install the module :)

[ygrenzinger]

Hello,

I lost some time because I forgot to install this node mode (but using it in Karma).

The error was misleading because I saw in Karma logs:
PhantomJS 1.9.2 (Linux) ERROR
SyntaxError: Parse error
at /usr/local/hudson-data/workspace/ecom360-sibo360/src/main/webapp/view/menu.html:1
PhantomJS 1.9.2 (Linux): Executed 0 of 0 ERROR (0.351 secs / 0 secs)

For the next users, maybe there can be made a small improvement there like "you really should install the node modules preprocessor" ;)
