Don't write a <ContentVersion> tag with an empty <LabelText> (#2191).

I can't see the problem with this, but apparently Dolby
CineInspect complains about it.

We could fix this in libdcp but I think that would make more sense
if this were related to a definite standard violation, instead of
just some tinkering to hide a possibly-incorrect warning.
