[Test] TableManagerITCase.testPartitionedTableManagement is not stable

Two unstable error in this test:

1. `Error: Failures: Error: TableManagerITCase.testPartitionedTableManagement:379->lambda$testPartitionedTableManagement$11:381 Expecting an empty Optional but was containing value: {0=[0], 1=[1], 2=[2], 3=[0], 4=[1], 5=[2], 6=[0], 7=[1], 8=[2], 9=[0], 10=[1], 11=[2], 12=[0], 13=[1], 14=[2], 15=[0]} `

Start with com.alibaba.fluss.server.coordinator.TableManagerITCase.testPartitionedTableManagement, especially lines 358 and 379, and inspect the waitValue calls in CommonTestUtils.java. Reproduce the failing test and trace both the missing partition and unexpected Optional; done means the test passes reliably for the partitioned-table cases.
