Weird behaviour with StreamsGetAll

[tsvilans]

Step 0:

• I've read the contribution guidelines!

Expected Behaviour

Getting all streams for a user should be GET <server>/streams.

Actual Behaviour

This fails with a 400 response ("Something went wrong.").
Adding ?omit=objects makes it work. Something goes wrong when it tries to include the objects in the stream list.

Affected Projects

Core, server.

Reproduction Steps & System Config (win, osx, web, etc.)

Proposed Solution (if any)

For now, adding ?omit=objects makes it work.
