console: Rollback old http stream

[PavelJankoski]

Summary

There was an error when trying to import end devices(or calling any other http stream endpoint), because the logic for http streams was removed during web socket changes.

Changes

Rollback of the old logic for http stream.

Testing

1. Go to console.
2. Go to /console/applications/:appId/devices/import.
3. Import a file.
4. Error should not be shown and everything should work like before.

Rolling back is great but we also need to make sure that this is now checked in the frontend tests.

Indeed the template converter also uses server side events. I'm also curious how this got through the end-to-end tests. Did you maybe merge before they completed?

Not sure, the ws PR was standing there for some time, the checks should have finished 🤔
