Description

We are currently sending currentScans and totalScans to the UI with the actual values of what’s happening. The UI shows sites scanned, which is different from total scans.

For example, if you add two names and one address, let's say we have only Verecor and Veriforia as brokers. We will send totalScans = 4 (two scans on Verecor, two scans on Veriforia)

Now we send the scans by broker. In the example above, we would show totalScans = 2 (we only count the brokers Vercor and Veriforia).

One thing is that we will count a broker as ‘scanned’ if one of the profile queries for a particular broker has a scan date. The reason is that if we wait for all profile queries for a particular broker to finish to mark it as scanned, the user could see matches for more than one broker even when the count is one.

Example of the above:

• Broker Profile query 1 (John Doe, broker#1)
• Broker Profile query 2 (John Doe, broker#2)
• Broker Profile query 3 (Sean Doe, broker#1)
• Broker Profile query 4 (Sean Doe, broker#2)

If the first queries return matches, the count will be 1..2, and we will show matches for two brokers which could confuse the user.

NOTE: This PR also fixes a bug where if there were multiple matches for the same broker profile query, it would only show one.

Steps to test

1. Start PIR from scratch (delete all data)
2. Create a profile with different names and addresses
3. The UI should show 1…to the amount of brokers (atm is 17)

Test matches are correct

1. Start PIR from scratch (delete all data)
2. Create a profile with different names and addresses, search a profile that has multiple profiles for the same query
3. The UI should show all the matches found

LGTM, tried many different combinations of names and addresses and the number there looks good. well done
