Issue #1066 - Fixed automatic type detection issue for edge properties

[prithvinambiar]

Issue #1066

1. getOrCreatePropertyKey was getting called without the value and hence the code in the following file was not getting executed - JanusGraphDefaultSchemaMaker.java#L44. This resulted in the edge properties not having automatic type detection.

2. Added JUNIT tests for vertex and edge properties to verify auto data type detection

I observed this issue with edge property where we added property value as Integer but when I try to access the edge with property value with int through grrmlin, it doesnt give anything back where as if I use '' to make it string it gives it back.
Also my java application code returns the edge with this property value as of type String class next time i retrieve edge after creation.
This is on 0.2.0

However, I also observed the similar issue on vertex.
I created vertex with integer property value but when trying to get it through gremlin with int value it throws error indicating type need to be string.

Just wondering if this issue is applicable for vertex properties as well (may be specific to Integer values?)
