Subject: [PATCH] Fix crash with invalid WAV files (#1163) (#1164)

With specially crafted WAV files having the "id3 " chunk as the
only valid chunk, when trying to write the tags, the existing
"id3 " chunk is removed, and then vector::front() is called on
the now empty chunks vector.
Now it is checked if the vector is empty to avoid the crash.
