build: temporary build fix for subscriber docs
confuse Collection with database

Inconsistency with example:

Original gave an ensureIndex example with a "records" collection. Then used the same name as the "records" collection as the name of the database. A bit confusing. Might be better to keep names consistent if people plan to work through the docs IMHO
