There's some weirdness in how we clean and standardize alias calls that's mapping correct id's to "undefined" string distinct id's. Today we nullify distinct_id and distinctId while keeping distinct_id in the properties object. In enqueue(), there's a:
if (message.distinctId) {
message.distinct_id = message.distinctId
delete message.distinctId
}
that seems to protect against incorrect/null/undefined distinct_id's but that doesn't work if we flush it out already in alias().
