download described as upload in an error message what is a bit confusing

[mkoniecz]

What steps will reproduce the problem?

1. Have large GPX path (in my case - I searched using overpass turbo for descriptive name (name=Boisko + leisure=pitch, duplicated layer and turned duplicate into GPX path)
2. Used "Download from OSM along this track"
3. Start editing while download works
4. Upload changes

What is the expected result?

Upload works or errors with nonmisleding error message

What happens instead?

"A background upload is already in progress. (...)" error message appears.

Please provide any additional information below. Attach a screenshot if possible.

in background download process happily marches on. My upload from JOSM got completed and changeset closed long time ago - ​https://www.openstreetmap.org/changeset/67679812 (I did it before starting download along track).

Changeset was closed by JOSM itself (one second after it was created), not by timeout.
