Review request for atlas and Madhan Neethiraj.
Bugs: ATLAS-2214
https://issues.apache.org/jira/browse/ATLAS-2214
Repository: atlas
Description
-------
```java
// When string/boolean attributes use the following sequence of filtering
on AtlasVertex attributes then the code
// runs into NPE
// 1. boolean attr "x" != false/true | boolean attr "x" == false/true
// 2. boolean attr notNull 'query.has("x") | boolean attr isNull
'query.hasNot("x")'
// whereas if the sequence is reversed then the NPE is not encountered
// Similar behavior is exhibited for the string attributes
// Workaround is to allow null == null value comparision
```
