Type check for userId in Javascript (Browser/Node) SDKs

The customer (Yuliyan Yordanov from Tesco Stores) suggested a failsafe solution to reject empty string userId upon activating/enabling an experiment/feature:

"A simple check for (typeof user_id ===’string’ && user_id.length ) would fix the issue from bucket side, and reject the decision, instead of meaningless data being generated and users being bucketed when they shouldn’t. Just a suggestion for a failsafe."

    Good idea! We'll consider this as an enhancement to our JS SDK
