fix: honour rules and slideshow when importing a umap file

Side note (for another PR I'd say): this usually occurs on a non
saved map, but in case the map already exist and is in sync mode,
should we sync each property (safer but one call per property)
or the whole properties object (lighter, but may override unwanted
things in remote, and currently there is no method to do so).
