When null safe dereferencing is used in second (and later) condition it throws NPE.

Version-Release number of selected component (if applicable):
Drools 6.0.0.Beta2, Drools 6.0.0-SNAPSHOT (2013-05-31)

How reproducible:
run NullSafeDereferencingTest as submitted in pull request #203

Steps to Reproduce:
1. run the code

Actual results:
Null pointer exception caused by mvel optimizer

Expected results:
Everything runs fine

Additional info:
The test runs fine if (address != null, address.street == $street) is used. Also it works fine if null safe dereferencing is used in first condition.
