tdf#120703 PVS: nullptr dereference
V595 The 'GetMedium()' pointer was utilized before it was verified against nullptr.
Check lines: 435, 455.
bURLChanged is only meaningful when GetMedium() is not nullptr;
otherwise bSaveDS could become true where no medium existed,
and dereferencing GetMedium() to find its URL would segfault.
