Remove explicit use of ./node_modules/.bin

npm's "scripts" functionality automatically adds executables from required libraries to the path when invoked.

Hence, there is no need to use the explicit "./node_modules/.bin/mocha" as just "mocha" will do. As per https://www.npmjs.org/doc/misc/npm-scripts.html#path (and I also tried it, just to make super sure :-) )


Feel free to ignore this, I just noticed it on the way through :-)
