Actually I think that "make $(DOMAIN).pot-update" would have worked for gnome-online-accounts. From po/Makefile:
# This rule has no dependencies: we don't need to update $(DOMAIN).pot
# at every "make" invocation, only create it when it is missing.
# Only "make $(DOMAIN).pot-update" or "make dist" will force an update.
$(srcdir)/$(DOMAIN).pot:
$(MAKE) $(DOMAIN).pot-update
I can't tell, though, if that's the case for all packages where dh_translations runs make() to create the .pot file.
