[fix][test] Fix the flaky tests of ManagedLedgerImplUtilsTest

[codelipenghui]

Motivation

If the trim ledger happened before get the ManagedLedgerImplUtils.asyncGetLastValidPosition(), the returned message ID will not be the message ID returned to the writer because messages are deleted by the trimming task.

Modifications

Set retention policy to the managed ledger to avoid the data deletion before the verification of the test. Otherwise, the test will not cover the newly added method.
