ci: Re-enable and fix NSE test

Makes https://github.com/matrix-org/matrix-rust-sdk/issues/3411 less bad because it should fail fast. It also seems to make it fail less often, so it might be worth re-enabling the test (which this PR does)...

NSE test is ignored (because it's flaky)

6

We disabled the NSE test in https://github.com/matrix-org/matrix-rust-sdk/pull/3409 because it was freezing up and timing out. This issue is to cover the work to de-flake and re-enable it.

3

Part of https://github.com/matrix-org/matrix-rust-sdk/issues/3542 Fixes a mistake I made in https://github.com/matrix-org/matrix-rust-sdk/pull/3556 - I included `device_keys` in the `content` and it should be outside as per [MSC4147](https://github.com/matrix-org/matrix-spec-proposals/pull/4147)
