Update indexes when associated entities are modified

[m-r-c]

The current version of the plugin (0.0.4.6) does not trigger an index update when modifying/inserting/deleting associated entities (e.g. from a one-to-many relationship).

For example, in the following dummy structure, updating an instance of B directly will not trigger an index update.

class A {
  static searchable = {
    children component: true
  }

  String name
  static hasMany = [children: B]
  ...
}

class B {
  static searchable = {
    root = false
  }

  String name
  static belongsTo = [parent: A]
  ...
}

...
A a = new A()
B b1 = new B()
B b2 = new B()
a.children << b1
a.children << b2

a.save() // index updated

a.name = 'bla'
a.save() // index updated

b1.name = 'b1'
b1.save() // index NOT updated

This is due to the following code from AuditEventListener.groovy

if (elasticSearchContextHolder.isRootClass(entity.class)) {
  pushToIndex(entity)
}

The associated entity is not the root class for the index, and so no updates are triggered.

The change in this pull request will traverse the entity relationship hierarchy (as long as the associated entities have back references to their parent) to find the root entity.
