@ayrat555 mox tests are in a failed state

@ayrat555 endpoint works very slow now: > 10 sec. It looks like it doesn't take data from cache but makes a query on DB on call, does it?

[ayrat555]

@vbaranov I just checked it. And it fetches from the db on the first call. All other calls use a cached value. It re-fetches value after global_ttl. What is the value of ADDRESS_SUM_CACHE_PERIOD env var?

@ayrat555 1 minute in my test. What is the problem to keep this endpoint async? This endpoint will be used by exchanges. And there will be downtime if it will be called at the time of cache updating. I urge to keep this endpoint async and fix tests for it instead of making it synchronous. I don't see the problem if it will return 0 on the first call. This is less painful than to have a synchronous endpoint, I think.

@vbaranov I addressed your comment. Now this PR just fixes tests
