300% benchmarks regression between Dec 13 and 14

[JaroslavTulach]

There is a huge regression in many engine benchmarks and some stdlib ones between Dec 13 and Dec 14:

• Investigate - caused by case of and intersection types #11850
• Fix

[JaroslavTulach]

The regression has happened between following commits e9b0ba9 and e9b0ba9 which leaves us with only one suspect:

• which identified the only culprit to be case of and intersection types #11850

    `aggregate ..Sum` of integer column remains integer and handles overflow (#11860)
    
    - This was mentioned in #7192 but didn't get a proper ticket.
    - Ensuring that summing integers gives an integer and not a float.
    - Only in-memory, as in Database the result type is database-dependent and we want it to be like that.
    - Also allowing the integer sum to overflow and become a `BigInteger`, in that case the resulting column will become `Decimal`.

    Fix sending same refreshToken as accessToken in open project request (#11862)
    
    In `open_project` request body we send `cognitoCredentials` for the project to be able to communicate with Cloud API. Currently the `refreshToken` has the same value as `accessToken` making that communication buggy.
