Preserve interrupt status when wrapping InterruptedException

[sohamgulame]

UncheckedFutureImpl currently clears the thread interrupt status when catching
InterruptedException and wrapping it in UncheckedInterruptedException.

This PR restores the interrupt status by calling Thread.currentThread().interrupt()
before throwing the unchecked exception, in accordance with Java concurrency best
practices.

A unit test has been added to verify that the interrupt status is preserved.
All tests pass locally with the Maven build.

Hello @sohamgulame
Just look at Jira and GitHub. Jira ticket are usually linked to a PR. Otherwise, look at the recent PRs.

Thanks for the feedback — understood.
I wasn’t aware that #1590 already covered the interrupt-handling change, and I agree these should not have been combined.
