Confluence V2 Space endpoints 500 on some spaces when using 'include-icon' query param

Issue Summary

This is reproducible on Data Center: (yes) / (no)

Steps to Reproduce

1. Use Confluence V2 API - Space endpoints
   1. wiki/api/v2/spaces
   2. wiki/api/v2/spaces/{id}
2. Add include-icon=true query param
3. With certain spaces, endpoint will respond with 500 / INTERNAL_SERVER_ERROR

Expected Results

The space endpoint(s) should not 500, regardless of the space(s) being accessed or query param being used.

Actual Results

The space endpoint(s) do 500, on certain spaces when the include-icon=true query param is true.

Workaround

Use V1 Get Spaces API, with `expand=icon` query param. This is not ideal, as this API is deprecated.
