set name and path in module init

[khassel]

This is a solution for #3708

I set it to draft because I'm not sure if it should be merged.

With this change the this.name will now work in the init function but for get this working in a module you have to copy the content of the node_helper init into your module. This is nothing new, you have to do the same for e.g. start.

AFAIS the used construction in js/class.js misses inheritence for this.

test fails will be fixed with #3709
