Displays all errors on map when come from issues sheet

[vinber]

For example, restaurants !

• http://osmose.openstreetmap.fr/fr/issues/open?item=8240
• i want to see the map, I clic on map :)
• i cant' see nothing because severity by defaut is "high"

what I expected, see restaurant :) so Severity=low or if simplest severity=all
