[[patchwork][PATCH] models.py: Improve Series naming when no cover letter is provided

[Jose Lamego <jose.a.lamego@linux.intel.com>]

The number/order prefix from a patch Subject line
is inapropriately included when naming a Series where
a cover letter is not provided and an additional
prefix is present at the Subject.

This change improves the substitution regex to omit
the number/order prefix but include any other prefix
that may be present.

[YOCTO #11305]
