SpecificationComposition reversed predicates

[rideliner]

It appears that lhs and rhs were reversed in 25924d8.

https://github.com/spring-projects/spring-data-jpa/blob/master/src/main/java/org/springframework/data/jpa/domain/SpecificationComposition.java#L54

This causes spec1.and(spec2) to result in spec2 and spec1.

Does this matter? The order of execution is determined by the execution plan created by the database, not by the order of statements in the SQL statement, isn't it?

The issue affects also OR concatenation.
