[JanusGraph] Fixed - should contain id property

[Tin-Nguyen]

Description

This is the fix related to my comment in #230 (comment) about the issue I'm facing in my Java application using spring-data-gremlin working with janusgraph database

java.lang.IllegalArgumentException: should contain id property

Gremlin-driver: 3.2.4
spring-data-gremlin: 2.1.7
Spring Boot: 2.1.8.RELEASE

Root cause

• The issue happened after the library finished inserting the new data into JanusGraph database.
• gremlin-driver returns a different data structure, like as below
  
  That's why validate() function raises IllegalArgumentException when it identifies there is no id, label, type, etc... contained in the Result instance.

I'm going to write some Tests to cover the logics and test it via my application shortly today.

I found another issue related Edge id field returned from JanusGraph

id value isn't Integer type, it's the map with relationId: <String>

[Tin-Nguyen]

I'm facing another issue when getting the data from JanusGraph using findAll() function. The data structure returned from gremlin-driver is quite different as the code is doing

Need to fix it as well

[superrdean]

@Tin-Nguyen Travis-ci seems not to pass, please check it and fix it.

[Tin-Nguyen]

@neuqlz I'm going to fix the PR within next week. I will let you know once it fixed soon. Thanks.

Hi everyone, I am new to open source development but I have a fair enough problem solving background in Graphs, this looks like an interesting project to start my open source contribution journey. It would be great if you could point me in the right direction to get started.

[nuspy]

Commented code to be eliminated.
Absolutely important changes, affect OrangoDb too.

[Tin-Nguyen]

sorry guys, I was busy with some urgent works. it's time to back to get this change done within next week.

is this branch ever going to merge ? this is a highly needed issue fix, one can not get started with it since it does not assure it will save.

[Tin-Nguyen]

@arvind-das sorry for the delay, I will try to improve the test coverage and merge the PR this weekend.

Thanks for the update Tim. I know you are busy in your work office work too. Meanwhile I created some generic methods to do my job. They solved the problem for a short time , still need to handle a lot of conditions. Once you merge this, I will be integrating thins into my app.
