GH-3230: MMIH: Fix Pausable/Lifecycle Methods

Resolves https://github.com/spring-projects/spring-integration/issues/3230

Previously, methods with the same name as `Lifecycle` methods were unconditionally ignored.

- Use logic similar to `ControlBusMethodFilter` to explicitly compare the candidate Method
  to those on `Paused` and `Lifecycle` and only ignore those.
- Explicitly disallow these methods when named - previously the check was only performed
  if no method name was supplied.

* - reinstate `Pausable/Lifecycle` methods if explicitly requested.
- log `Pausable` methods that are not candidates.

* - Fix typo in test method.

**Cherry-pick to 5.2.x**
