AFAICT, this never worked before because everything was serialized into `content["org.matrix.opentracing_context"]`
but `start_active_span_from_edu` read from `content["opentracing"]`.
See https://github.com/matrix-org/synapse/pull/5852#discussion_r934960586
Do we even still want this?
Previously, `_resolve_state_at_missing_prevs` returned the resolved
state before an event and a partial state flag. These were unwieldy to
carry around would only ever be used to build an event context. Build
the event context directly instead.

The `incoming-federation-request` vs `process-federation_request` was first introduced in
https://github.com/matrix-org/synapse/pull/11870
- Span for remote trace: `incoming-federation-request`
- `child_of` reference: `origin_span_context`
- `follows_from` reference: `servlet_span`
- Span for local trace: `process-federation-request`
- `child_of` reference: `servlet_span` (by the nature of it being active)
- `follows_from` reference: `incoming-federation-request`
Synapse 1.64.0rc2 (2022-07-29)
==============================
This RC reintroduces support for `account_threepid_delegates.email`, which was removed in 1.64.0rc1. It remains deprecated and will be removed altogether in a future release. ([\#13406](https://github.com/matrix-org/synapse/issues/13406))

Invalid type StreamToken for attribute value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types
```
Had to add a few more logs to find this instance since the warning doens't give much info where I am setting this invalid attribute.
This was good enough to find it in the code.
```
