Do not fallback to AND for FTS phrase operator.
If there is no positional information of lexemes then phrase operator will not fallback to AND operator. This change makes needing to modify TS_execute() interface, because somewhere (in indexes, for example) positional information is unaccesible and in this cases we need to force fallback to AND.
