[fix][test] Fix flaky ManagedCursorTest.testLastActiveAfterResetCursor and disable failing SchemaTest

[lhotari]

Motivation

After upgrading Mockito to 5.17, the test ManagedCursorTest.testLastActiveAfterResetCursor is very flaky.
There are two problems:

• the result callback gets triggered before the last active timestamp is updated
• the test assumes that calls will take more than 1 ms to complete

In addition, Pulsar CI is currently blocked since SchemaTest.testPendingQueueSizeIfIncompatible fails consistently. This issue is reported as #24262. To unblock Pulsar CI, the change is included in this PR.

Modifications

• update the last active timestamp before triggering the callback in ManagedCursorImpl
• add a 1 ms delay in the test code to ensure that the next timestamp is different than the current one
• disable SchemaTest.testPendingQueueSizeIfIncompatible

Documentation

• doc-not-needed
