Add ConditionToPatternTest : 1st round

Issue Description:

Currently tests in drools-ansible-rulebook-integration repo are mostly integration tests where JSON is input and matchedRule is asserted.

Then, tests for MapCondition.toPattern looks be a good candidate to add.

Acceptance Criteria:

Add tests for MapCondition/SmpleCondition to Pattern/predicate referring existing integration tests. Acceptance Criteria would be to cover all Expressions. (not exact all existing tests)
For 1st round,

• LogicalOperator
• RelationalOperator
• SelectExpression
• AdditionExpression
• Binding
• SimpleCondition
