Facebook adapter and WebView data directory

[dfretes]

It seems that when using mediation, FAN initializes its WebView on the same directory as the main Application's process. With changes in Android P, this crashes the application.

Fatal Exception: java.lang.RuntimeException: Using WebView from more than one process at once with the same data directory is not supported. https://crbug.com/558377
