Receiving multiple invitations in a short time with the same publisher

[AlexV525]

I was invited to the new publisher. However, multiple consent emails were sent to my account.

@AlexV525: Thanks for reporting this, we should deduplicate repeated invites.

I assume the person who did the invite clicked on it multiple times? How fast were these repeated clicks? Did they have any browser extension on that is worth mentioning?

@isoos It was on the mobile Chrome and probably with a poor network condition. The "Success" dialog also popped up multiple times as the person described.

With #8700 it seems that our current deduplication code is correct, but it may be failing because Datastore's eventual consistency returns the already created entities only after the repeated queries are processed.

We may need to use an additional method to detect duplicates, e.g. through reddit cache.
