WhereAdapter passes in the SELECT predict and not the parameter expression

[prb112]

In fhir-database-utils, WhereAdapter passes in the SELECT predict and not the parameter expression.

The following code is potentially incorrect, and the tests are disabled.

• groupByQuery
• orderByQuery

/**
     * Start building the GROUP BY clause
     * @param expressions
     * @return
     */
    public GroupByAdapter groupBy(String... expressions) {
        return new GroupByAdapter(select);
    }

    /**
     * Start building the ORDER BY clause
     * @param expressions
     * @return
     */
    public OrderByAdapter orderBy(String... expressions) {
        return new OrderByAdapter(select);
    }

Also WhereClause HavingClause's predicate is unused.
