DERBY-6351: Syntax error on equal transition table name and correlation name in
statement trigger
Change how CreateTriggerNode.bindReferencesClause() checks for the
lack of a correlation name. Instead of checking it indirectly (and
unreliably) by seeing if the table name matches the base table name,
check directly if the correlation name is null.

>
> If a reference to a transition table in a statement trigger has a correlation
> name, and that correlation name is equal to the name of the transition table,
> the CREATE TRIGGER statement fails with a syntax error.
> To reproduce:
> {noformat}
> ij version 10.10
> ij> connect 'jdbc:derby:db;create=true';
> ij> create table t1(x int);
> 0 rows inserted/updated/deleted
> ij> create table t2(x int);
> 0 rows inserted/updated/deleted
> ij> create trigger tr1 after insert on t1 referencing new table as n insert
> into t2 select x from n as n;
> ERROR 42X01: Syntax error: Encountered "as" at line 1, column 89.
> Issue the 'help' command for general information on IJ command syntax.
> Any unrecognized commands are treated as potential SQL commands and executed
> directly.
> Consult your DBMS server reference documentation for details of the SQL
> syntax supported by your server.
