Clear interrupted status of a thread in test

`RetryWithDelayTest#throwsWhenSleepInterrupted()` test mocks throwing of
`InterruptedException` and triggers handling code to restore the interrupted
status. This caused some subsequent tests to fail because they still saw
current thread as being interrupted.

This commit adds clearing of the interrupted status to the test.
