dogg3rz insert node doesn't update mtimes when new node is inserted

[adpadilla]

The scenario is as follows:

1. create a new dataset
2. insert a node (into default graph)

The state of the json-ld doc are as follows for each step. Notice that the number of mtimes entries stay the same after the insert node operation.

after create dataset:

{
   "__dgrz_mtimes__" : {
      "9dcf97a184f32623d11a73124ceb99a5709b083721e878a16d78f596718ba7b2" : 1615752686707369000,
      "25dfd29c09617dcc9852281c030e5b3037a338a4712a42a21c907f259c6412a0" : 1615752686707369000
   },
   "@graph" : [],
   "@context" : {}
}

after insert node(default-graph):

{
   "@context" : {},
   "@graph" : [
      {
         "@id" : "_:b4879502-17b5-4418-80c0-3f7df44dbe52",
         "attr1" : "value1"
      }
   ],
   "__dgrz_mtimes__" : {
      "25dfd29c09617dcc9852281c030e5b3037a338a4712a42a21c907f259c6412a0" : 1615752686707369000,
      "9dcf97a184f32623d11a73124ceb99a5709b083721e878a16d78f596718ba7b2" : 1615752686707369000
   }
}

@bhallamp I see see the same issue where only 2 entries are in __dgrz_mtimes__ after inserting a node. Expect 3.
