Ensure index commit released when testing timeouts (#39273)
This fixes #39245. Currently it is possible in this test that the clear session call times-out. This means that the index commit will not be released and there will be an assertion triggered in the test teardown. This commit ensures that we wipe the leader index in the test to avoid this assertion. It is okay if the clear session call times-out in normal usage. This scenario is unavoidable due to potential network issues. We have a local timeout on the leader to clean it up when this scenario happens.
