GET a file while it's in processing doesn't return 425 code (async uploads)

[saw-jan]

Steps to reproduce

1. Start oCIS with these envvars:

PROXY_ENABLE_BASIC_AUTH=true \
STORAGE_USERS_OCIS_ASYNC_UPLOADS=true \
OCIS_EVENTS_ENABLE_TLS=false \
POSTPROCESSING_DELAY=30s \
./bin/ocis server

2. Upload a file

curl -XPUT "https://localhost:9200/remote.php/dav/files/admin/lorem.txt" \
-d"uploaded" -uadmin:admin -vk

3. Try to GET the file using old, new and spaces endpoints

Old

curl -XGET "https://localhost:9200/remote.php/webdav/lorem.txt" -uadmin:admin -vk

New

curl -XGET "https://localhost:9200/remote.php/dav/files/admin/lorem.txt" -uadmin:admin -vk

Spaces

curl -XGET "https://localhost:9200/dav/spaces/5c3aacd7-e23d-43b0-89ec-ca4c67ae02ef%24cae6d2cf-a0dc-4e1a-8354-20b74ef12f34/lorem.txt" \
-uadmin:admin -vk

Expected behavior

to return status code 425 as mentioned in #4095 (comment)

Actual behavior

returns 500 internal server error
