Only pass forwardedRef to children if options.withRef is false

[emroussel]

forwardedRef was always passed down to its children in #992, but as pointed in the comments, it should only be passed down if options.withRef is false (if it is true, we want to pass the ref as ref and remove forwardedRef from props) and if forwardedRef is defined.

Coverage decreased (-0.2%) to 95.238% when pulling 90f446b on emroussel:withTranslation-forwardedRef into 0c589dd on i18next:master.
