Better error message for undefined values

Hello,

if possible I think it would be great if you could get better error messages if you accidentially pass undefined as parameter. Especially the query and the arguments would probably be helpful. Currently it seems like you get something like the following:

May 25 22:13:53 arch-luks2 node[11410]:       throw Errors.generic('UNDEFINED_VALUE', 'Undefined values are not allowed')
May 25 22:13:53 arch-luks2 node[11410]:                    ^

Start by tracing undefined-value handling in src/types.js, then inspect the query construction paths shown in src/query.js and src/index.js. Compare the current error path with the requested query and argument context; done means undefined parameters produce a more useful error while preserving existing behavior and tests.
