GH-8685: Re-fetch group after setting condition (#8686)

* GH-8685: Re-fetch group after setting condition

Fixes https://github.com/spring-projects/spring-integration/issues/8685

The `AbstractCorrelatingMessageHandler` updates the group metadata in DB
not only for provided `condition`, but also a `lastModified` field.
A subsequent scheduling for group timeout takes the `lastModified`
to compare with the value in the store after re-fetching group in task.
This does not reflect reality since adding `condition` modifies the data in DB,
but in-memory state remains the same.

* Re-fetch a group from the store in the `AbstractCorrelatingMessageHandler.setGroupConditionIfAny()`.
* Verify expected behavior via new `ConfigurableMongoDbMessageGroupStoreTests.groupIsForceReleaseAfterTimeoutWhenGroupConditionIsSet()`

**Cherry-pick to `6.1.x`, `6.0.x` & `5.5.x`**

* * Fix Checkstyle violation in the test
