Removed unneccessary JOIN in "create_interest_snapshot"(...)

The INSERT INTO "direct_supporter_snapshot" in function "create_interest_snapshot"(...) does not need to check if members are active.
The previous step ensures that the joined table "direct_interest_snapshot" does not contain entries from disabled members.
