Cannot update `endDate` and `completionDate` of milestone.

[maxceem]

When try to update endDate orcompletionDate of a milestone get validation error:

validation error: \"endDate\" references \"startDate\" which is not a date

For example, PATCH /v4/timelines/20/milestones/19 with the next body:

{
  "param": {
    "endDate": "2018-07-30T11:12:09.000Z"
  }
}

Returns the error above. Same if try to update completionDate.

This is fixed @maxceem. Let me know if it is still not working for you.

Verified in dev. It seems to be working fine. Still, if is not for some particular case, we can reopen the issue.

@vikasrohit It's fixed for completionDate but not for endDate. Server returns validation error: "endDate" is not allowed.

@maxceem as per our updated strategy, we are not going to allow updates to the startDate and endDate fields of a milestone via REST endpoints, it would be automatically when doing other lifecycle updates to the timeline or other milestones.
