[yocto] [patchwork][PATCH v4] patchwork.models: Include first patch's name in series name

[Jose Lamego]

Patch Series created without a cover letter are named using a
non-descriptive generic string.

This change names the series using either the first 30 characters in
patch #1 plus the remaining patches number, or the patch name for
one-patch (1/1) series.

[YOCTO #10625]
