Fixed LP bug #668290.
Prohibited to use hash join algorithm BNLH if join attributes need non-binary collations. It has to be done because BNLH does not support join for such attributes yet. Later this limitations will be lifted. Changed default collations for the schemes of some test cases to preserve the old execution plans.
