Fix free-after-use for MediaHTTP

        extHeaders.add(String8("User-Agent"), String8(MakeUserAgent().c_str()));

    }

    bool success = mHTTPConnection->connect(uri, &extHeaders);

    mLastURI = uri;

    // reconnect() calls with uri == old mLastURI.c_str(), which gets zapped

    // as part of the above assignment. Ensure no accidental later use.

    uri = NULL;

    bool success = mHTTPConnection->connect(mLastURI.c_str(), &extHeaders);

        AString sanitized = uriDebugString(mLastURI);

        mName = String8::format("MediaHTTP(%s)", sanitized.c_str());
