Omit object from t function

[pedrodurek]

Closes (probably): i18next/react-i18next#1559, i18next/next-i18next#1795

There is one downside about the approach proposed here. t function will no longer return object unless the option returnObjects is true. This is not applicable if t function is fully type-safe (https://www.i18next.com/overview/typescript), with the enhanced types, we can infer the exact return type.
