v1.6.4 (regression) `not currently running on the Tokio runtime.` crash

[sync]

When using the latest async std version:
async-std = { version = "1.6.4", features = ["attributes", "tokio02"] } and tokio02

I get an error message deep down saying not currently running on the Tokio runtime.

I rely on the tokio02 feature so I can keep using https://crates.io/crates/cloud-pubsub that has a dependency on the Tokio runtime.

If I use 1.6.3 instead, I don't get the error
async-std = { version = "=1.6.3", features = ["attributes", "tokio02"] }

I looked at the latest release note and I see nothing related to a potential tokio02 change that might explain why I now get this crash.

I'll attach a sentry crash report and happy to provide further details if necessary

I'm working on fixing this

From my testing, works fine both from within local and global tasks now

@sync while waiting for a release, if you declare a dependency on async-global-executor 1.2.1 with tokio02 feature enabled (as it's disabled by default), async-std should work properly
