QuerySpecification doesn't support selecting non-lowercase columns

[bivapa]

Expected Behavior

When I define a repository method signature with a QuerySpecification parameter and I construct a QuerySpecification instance like below with a select statement over non-lowercase columns I expect the columns values to be set on the result entity object.

QuerySpecification<Entity> qs = (root, query, criteriaBuilder) -> {
    query.multiselect(root.get("foo"), root.get("bar"));
    return criteriaBuilder.equal(root.get("foo"), "foo");
};

Actual Behaviour

When I define a repository method signature with a QuerySpecification parameter and I construct a QuerySpecification instance with a select statement over non-lowercase columns Micronaut Data JDBC doesn't set the columns values on the result entity object.

Steps To Reproduce

1. Clone the example application
2. Run ./mvnw clean test to get the test querySpecificationTestLowercaseColumn pass and querySpecificationTestUppercaseColumn fail
