fix(donor): user which as same id as donor can see donor history

[ravinderk]

User Story

As a donor, I want do not want anyone to access my history.

Matt Research:

So, after going through all of that I finally found what is most likely the problem. 

1) User A's User ID is 123, and he has NO Donor account, and he sees Donor A's donations. Donor A has NO user account and his Donor ID is 123. 

2) User B's User ID is 124, and he has NO Donor account. He seesDonor B's Donor history and Donor B's Donor ID is 124.

So the glitch is that WordPress users who have NO Donor account see the Donation History of the Donor that has the same User ID number (if that User ID exists). That is something that I could most likely replicate and we can get a fix out for that because that is definitely not the intended behavior at all.

Current Behavior

If the user has the same id as a donor can see donor's donations on the history page.

Expected Behavior

Only donor or connect user has access to donation history
