work: give bodged background tasks some time to complete

	if ( not $self->app->config->{traewelling}->{separate_worker} ) {

	# add_wagonorder and add_stationinfo assume a permanently running IOLoop

	# and do not allow Mojolicious commands to wait until they have completed.

	# Hence, some add_wagonorder and add_stationinfo calls made here may not

	# complete before the work command exits, and thus have no effect.

	#

	# This is not ideal and will need fixing at some point.  Until then, here

	# is the pragmatic solution for 99% of the associated issues.
