Fixed a bug in the code of the patch for WL#24 that manifested

itself when running the pbxt.group_min_max test leading to
wrong result sets and execution plans for many test cases.
When evaluating the index merge scans the code ignored the following:
if an index merge contains a range tree, such that none of its
SEL_ARG trees represents index ranges, then the index merge must be
discarded as not usable for any index merge retrieval.
