Bug#1076797: DDPO: VCS column marked as failed unexpectedly

[Fab Stz <fabstz-it@yahoo.fr>]

Package: qa.debian.org
Severity: normal

Dear Maintainer,

On my DDPO page [1] there are some packages for which the VCS column shows
"failed" however, the "debian/latest" branch in itself didn't fail but the
pipeline failure is on another branch "ubuntu/focal" for instance.

In the pipeline list of salsa, it is even not the latest job that failed which
could have explained that, but the one on ubuntu/focal.

Moreover, if I delete the failing pipeline from salsa (this is the case for
php-datto-json-rpc), it is still marked as "failed" (I deleted the job
yesterday and today DDPO still shows it as "failed").

Packages are:
        php-datto-json-rpc
        php-datto-json-rpc-http
        php-giggsey-libphonenumber

I would have expected the failure statut be the one of the branch that holds
the debian tree (eg. main, master, debian/latest...) or as an alternative the 
branch marked as "default" in salsa.
