[BUGFIX] History service does not show details anymore

The history service in the workspace module does not contain
any details for modified records.

There are two things that result in this behaviour:
* the history service works on the live record and automatically
  resolves the workspace version
* the security fix in #42696 introduces a permission check for
  pages (which is -1 if using the workspace version directly)

Thus, the reference to the live record needs to be used instead.
