[yocto] [patchwork][PATCH] 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 the first 30 characters in
patch #1 and the remaining patches number.

[Yocto #10625]
