Rename dump_sql_statement() calls to dump_to_sql_statement()
Rename dump_sql_statement() calls to dump_to_sql_statement()

This effects cases where drop_database=False, which, in many cases,
will cause etlalchemy to UPSERT rows into the Target DB, rather than
blow the DB away and start fresh.

This UPSERT feature, to my knowledge, was broken as of the last
release because of this undefined function name above.

This case was never reached b/c it only occurs when some rows
are updated, with the remaining 'new' rows being inserted. It is
in the 'insert' step of the upsert operation that this function
gets called.

I have renamed the function call to reference the correct function,
so upserts should now work.
