fix: explicitly set DB option to suppress deprecation warning

The value we set is the current default for Mongoose 6, but
the default will change to false in Mongoose 7. Therefore the
warning was popping up.

The more conservative option is false, meaning invalid
query parameters do NOT result in entire collections
getting returned.
