eth/filters, p2p/simulations: fix benchmarks (#23806)

Some benchmarks in eth/filters were not good: they weren't reproducible, relying on geth chaindata to be present.

Another one was rejected because the receipt was lacking a backing transcation.

The p2p simulation benchmark had a lot of the warnings below, due to the framework calling both
Stop() and Close(). Apparently, the simulated adapter is the only implementation which has a Close(),
and there is no need to call both Stop and Close on it.
