19316	Don't show warning when a new empty relation is deleted	GerdP	team	"==== What steps will reproduce the problem?
1. Select a closed way tagged building=yes
2. Press Ctrl+B accidentially (create a multipolygon relation and remvoes the tags from the way)
3. Edit other things so that undoing step 2. is not a nice option
4. Try to fix the mistake without undoing all actions by removing the member from the relation and adding the tags again.
5. Try to remove the empty relation
==== What is the expected result?
new empty relation is deleted without warning
==== What happens instead?
Popup says that ""This step is rarely necessary and cannot be undone easily after being uploaded to the server.""
==== Please provide any additional information below. Attach a screenshot if possible.
I wondered why we have > 15.000 empty multipolygon relations with version 1 in OSM and most of them were created by JOSM. I guess the above steps and the wrong warning could be the reason.
