Upsert Can't handle required 'false' boolean values

[NoahDavey]

When trying to run upsert command, it errors if passing in a boolean attribute that is 'required' and is set to false. It seemed that the dynamo command created includes the attribute in ExpressionAttributeNames but did not pass through the value correctly into the ExpressionAttributeValues object, it instead sets it to undefined. This causes the following error to be thrown by the document client

ElectroError: Pass options.removeUndefinedValues=true to remove undefined values from map/array/set. - For more detail on this error reference: https://github.com/tywalch/electrodb#aws-error

I think I hunted down where the bug came from, it seems it was due to the following line short circuiting on the value of upsertAttributes[field] which was fine in most cases, except for when that value equals false in which case it looks for updatedKeys[field] and then value gets assigned undefined

const value = upsertAttributes[field] || updatedKeys[field];

Im not super familiar with the Electro codebase and just hunted this down with some logs etc, but please feel free to redo if what i have done would break anything. I just figured i could hopefully make a good start :)
