havePathsInCommon will always return false for nested objects

[itsramiel]

the havePathInCommon function of chapter 5 uses lodash intersection which will always return false.

data-oriented-programming/src/chapter05/paths-in-common.js

Lines 1 to 4 in 07bf95b

	function havePathInCommon(diff1, diff2) {
	return !_.isEmpty(_.intersection(informationPaths(diff1),
	informationPaths(diff2)));
	}

havePathInCommon uses informationPaths which returns an array of the paths, where each path is an array with keys as values of the array.

A return value example of informationPaths would be:

[
  ['library', 'catalog', 'authorsById', '1', 'name'] ,
  ['library', 'userManagement', 'userssById', '1', 'name'] 
]

but lodash's intersection will not deeply check this nested array, so if the above path was compared with

[
  ['library', 'catalog', 'authorsById', '1', 'name'] ,
]

It will return false because arrays are reference type.
