Suppress NO_DATAFILE_SPECIFIED error when sdkKey is present

[aflinky]

What I wanted to do

Create instance of Optimizely with sdkKey (function createInstance) and without a datafile

What I expected to happen

As it says in the docs, the param datafile is not necessary if sdkKey is present (and vice versa)

What actually happened

The enums.ERROR_MESSAGES.NO_DATAFILE_SPECIFIED ("No datafile specified. Cannot start optimizely.") is thrown. Even though this doesn't cause the creation to break, it throws an error to the console (that my company has suppressed using a combination of a custom logger and custom error handling).

Steps to reproduce

optimizelyClientInstance = optimizely.createInstance({
  sdkKey: <optimizelySdkKey>,
});
  
const result = await optimizelyClientInstance.onReady({ timeout: 10000 });
