When trying to build two linked reservoirs using the "draggable reservoir" feature, if the two reservoirs are in valid placements but the pathfinder does find a way for the aqueduct, the reservoirs displayed some footprints on the map as if they were building but they are not.
This PR proposes to change that so that footprints are shown only if they could be built.

After:

The call to
map_property_clear_constructing_and_deletedas, with that change, there does not seem to be any code path where bothplace_reservoir_and_aqueductswould return0and footprints would be shown on the map. Correct me if I am wrong though.This is a change from the original Caesar 3 so feel free to close it if it is out of scope.
