[yocto] [patchwork][PATCH 1/2] patchwork.bin.parsemail: Use oldest header references

[Jose Lamego]

References list for previous emails only include first found
header, causing that some root messages for series are skipped
and corresponding series revision numbering gets corrupted.

This change forces references list to use last header found,
allowing for Patch emails created with send-pull-request script
to be appropriately appended to last revision.

[Yocto #9941]
