BUGFIX: Throw PartialWorkspaceRebaseFailed if workspace was up to date and publish didnt work

[mhsdesign]

Resolves partially #5364

PartialWorkspaceRebaseFailed exception

Thrown if the partial publish/discard cannot work because the events cannot be reordered as filtered.

This can happen for cases like attempting to publish a removal first and wanting as remaining change
a node move out of the removed descendants or publishing a node variant creation before the node is created.

We cannot reliably detect these cases in advance but in case the workspace is up-to-date its most likely such
an ordering conflict.

To solve the problem the partial operation should be retried with a different filter or a full publish/discard is required.

If the workspace is outdated we cannot know for sure but suspect first that the conflict arose due to changes
in the base workspace, thus we throw WorkspaceRebaseFailed instead.
A forced rebase then might not solve the problem if It's because the order of events cannot be changed.
But attempting a second partial publish/discard (with up-to-date workspace) this exception will be thrown and can be reacted upon.

Shouldn't we merge this for now as a safety measure, not much we can do right now....

Okay i introduced a proper PartialWorkspaceRebaseFailed exception for this reorder case, added some documentation and a test for the issue with the move node and delete;)

now id say yes merge! The neos ui will still need some love making this a human readable error and also to offer a DiscardAll or PublishAll button (or maybe at some point publishAll parent nodes too ^^)

Mmmm, the test error seems legit, I'll have a look
