Subject: [PATCH] fix: do not fail when trying to read metadata of a missing
 geojson

Some geojson have been removed by mistake time ago (cf #1003), when someone
tries to load a map referencing them, it was until recently just
showing an error message, but since recently we try to get the
metadata from it, and this will crash.
