cups-browsed seems to set default print-color-mode to monochrome for Brother MFC-J430W

[peat-psuwit]

Brother MFC-J430W is a printer which support AirPrint.

The system is Ubuntu 20.04, running cups-snap in system mode. The snap is built from the git tip, plus https://github.com/OpenPrinting/cups-snap/pull/10 which fixes missing GS driver.

When simply using lp, the printer prints the file in monochrome. To let it print in color, one has to specify -o print-color-mode=color to lp.

Attached is access_log, cups-browsed_log, and error_log, collected fresh after restarting both cupsd and cups-browsed and then prints in both modes.

BTW, yes, I'm the same person reporting #426. Maybe it's related.

Re-tested with cups-snap 2.4.2-1 (760). The issue still persists.
