Fix try-runtime feature (#899)

[wischli]

I am currently working on a new feature for the Centrifuge Chain which requires adding a migration. Of course, I would like to verify this migration via try-runtime. Unfortunately, our repo is still on Polkadot v0.9.32. Moreover, we have PureStake dependencies to Moonbeam and your Frontier fork.

Since cargo patch does not support having the same source and destination yet, the only workaround for not having conflicting dependencies would be forking Frontier into the Centrifuge organization and patching to that destination. However, that is not clean.

Therefore, I would really appreciate if you could merge this cherry-pick which already exists on your master branch into the moonbeam-polkadot-v0.9.32 branch such that me and potentially others still depending on this branch can use try-runtime.

We are getting a look at it and will merge soon
