JOSM uses diff uploads, where either the whole upload works or the whole
What *should* happen in a case like yours:
1. you hit upload
2. upload fails, JOSM complains
3. if you try to exit JOSM, it should warn about unsaved changes
4. you must now do a download and resolve any conflicts
5. you hit upload again
6. it works
Unfortunately, step "4" will not send you deleted objects, so JOSM has
no way of knowing that the object has already been deleted. It could,
however, better evaluate the return value of step "2" to at least find
out that a certain way is giving trouble and maybe offer to leave that
out of the upload or so.
Currently the only way to deal with this situation is to save the file
in JOSM and then manually remove the "action=delete" attribute from the
way in question, before opening the file again and uploading it. There
is also a config option osm-server.atomic-upload=false that you can set
to make JOSM upload each object individually, which in your case would
have meant that some changes would at least have been stored.
I know this is very unsatisfactory and a fix is being worked on, but not

You can use the changeset browser on the openstreetmap.org site to find
out if a changeset has been created at the time in question and whether
it contains anything.
