Allow null jstring to C++ string conversions in release.
WebView has too many cases where apps can pass in a null java string and
have it reach native causing a crash. For now, put back the code that
returned empty string, but keep the DCHECK so that we still hit it on
bots that run with DCHECKs enabled. We'll fix WebView and have another
go at this in a later release.
