Fix serializeJson()

[marcoexplora]

This is the patch I created to solve the two missing imports on
#47

In serialiseModuleDefinition I had to add a double import ( maybe there is a cleaner solution but I didn't want to mess with the logic of the file)

    serializeFunctionalComponent = require('./serializeModule'),
    serializeModule = require('./serializeModule'),

I hope this helps

Thanks
