[BUGFIX] Avoid using BackendWorkspaceRestriction

When using BackendWorkspaceRestriction the DB query
fetches newly created records of ALL workspaces, not just the currently
given workspace.

For this reason it is highly discouraged to use this
restriction but use the main WorkspaceRestriction instead.

This change adapts all remaining places which especially
is relevant when having multiple NEW PLACEHOLDERs in various
workspaces to only work on the current workspace.
