Move recover authority logic inside submitted lambda

Since submit_eth_call_to_pool() is called from rust thread, blocking on
fiber promises is not appropriate and can lead to performance issues.
Move recovert_authorities() logic inside lambda executed in fiber pool.

Since eth call txn has single authority, parallelization logic inside
recover_authorities() only intoduces overhead without benefits. Replace
parallelization with single call to recover_authority().
