The tests fail a lot, e..g on appveyor. Example: https://ci.appveyor.com/project/ethereum/go-ethereum/builds/38784182/job/5so0ap0l4d3al810

It appears that a lot of goroutines are leaked. Just by running TestReceiptsAccessLes3, I got the dump below after doing the teardown.

THe changes in this PR might be doable more nicely, but I'm not really that well versed about how les works under the hood, so I just made the simplest changes I could find which "fixed" it.
