fix(map): a selected stay is flown to even when no pin stands for it

With the Unplanned filter on, a click on a stop in the day list moved the
map while a click on the stay chip did nothing: the map only went to a
selected place it showed as a pin, and the GL map also to one of the open
day's stops, which a stay is neither. Both renderers now look the target
up the same way, the pin first, then the day's stop, then the selected
place itself, so the map goes to the stay whatever filter hides its pin.
