fix: LogQuery panics on error

[0xZerohero]

Motivation

LogQuery is supposed to return stream of Results, but it panics on error.

thread 'main' panicked at /home/zerohero/Work/oob/ethers-rs/ethers-providers/src/toolbox/log_query.rs:120:44:

To reproduce the issue you can run the test in this PR on master.

Solution

We have to return Poll::Ready(None) to stop the stream after returning the error.
