[OSM-Photos] tiny workflow enhancement

[malenki]

I Ddon't know if I asked before but ir would be great not to have
selected pictures after they where loaded.

two points:
*When I have to mask sections at some pictures at first I have to
deselect all before I select the ones to edit.

*When I see there is nothing to mask, it's not much work to click
"select all" "Mark as safe" and "save" since this fields are close
together.

Don't know how the others work btu for me default no selected pictures
would be a lot better.
