[new-parser] Grouped accessors for nested objects broken

[yurloc]

Parent issue

• Experiment: New DRL parser #5678

Failing tests

• org.drools.model.codegen.execmodel.CompilerTest#testChainOfMethodCallInConstraintSub

Notes

• PATTERN_DSL only.

Rule code snippet

  $p : Person( address.(city.startsWith("I") &&  city.length() == 5  ) )

Error output
