Silence method redefined warning in aggregate update exception test

[suketa]

AggregateUpdateExceptionTest#with_conversion_raising replaces DuckDB::Converter._to_date with define_singleton_method and restores it the same way. Both steps redefine an existing method, so rake test prints:

test/duckdb_test/aggregate_update_exception_test.rb:39: warning: previous definition of _to_date was here

This removes the singleton method before each redefinition, so no warning is emitted. Test behavior is unchanged.

Minitest's stub was not used because Minitest 6 moved it into the separate minitest-mock gem.
