Add missing argument when checking for fleet delivery capability

[RBinsonB]

There is a small bug preventing the MiR fleet adapter to be used with delivery task. This PR aims to solve it.

If setting the delivery task capability to True in the config, the following crash would happen when trying to launch the fleet adapter:

ros2 run fleet_adapter_mir fleet_adapter_mir -c $CONFIG_FILE -n $NAV_GRAPH -d
Starting mir fleet adapter...

This is due to this function call : https://github.com/osrf/fleet_adapter_mir/blob/92c457d7713f5c12ccad1208a85d445d937c6635/fleet_adapter_mir/fleet_adapter_mir.py#L160

consider_delivery_request needs a confirmation for both pickup and dropoff. This is fixed in this PR.

This solution was tested successfully on a real MiR100. The fleet adapter is running and able to carry out delivery tasks.

Hi Team,

As referenced in Issue #30, I have not been able to get the fleet adapter working. Please let me know if I am missing anything.
