All non-guest account published to admin user.

[Akarshit]

Issue Description

When a admin logs in, all the non-guest accounts are published to the client. This causes the browser to hang as there could be large number of "customers".

Steps to Reproduce

1. Run reaction.
2. Register a account.
3. Log out
4. Sign-in as admin.
5. Check the minimongo database, in which the Accounts collection will have the account of the customer created in step 2.

Possible Solution

From here https://github.com/reactioncommerce/reaction/blame/12cd570f9460766e7adeb7f1625b4a954b8ae87e/server/publications/collections/accounts.js#L25
I see that initially we were not publishing "guest" and "customer", but now we are publishing the "customer" accounts, maybe we can just revert this as we don't show the "customer" accounts to the admin anywhere.

Versions

v 1.13.0

Clients of mine running a Reaction store with 29,000+ users are unable to log in as admin because of this issue. Literally noticed it yesterday, nice timing!
