[M137] [B4B] Fix getting default parent for managed nodes

Original change's description:
> [B4B] Fix getting default parent for managed nodes
> 
> Some operations are allowed for managed nodes, such as opening the
> bookmark manager after selecting a managed node through the context
> menu.
> 
> The code previously did not allow that since it assumed this was only
> used to get the parent to create new nodes, which is not allowed for
> managed bookmarks.
> 
> Add a method specific for managed nodes in the MergedService to
> expose that this is an accepted operation but that it should be
> treated differently than the regular nodes.
> 
> Fixed: 414129879

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
