Broken suggestions loading after library is downloaded

[Akirathan]

After #14553, loading of Standard.Image (which is now an extension library) immediately after the download of the library is broken.

To reproduce:

• Create new project
• Open code editor and paste from Standard.Image import all
• No suggestions for Image are loaded.

Search for "Unable to load suggestions" error message in enso-language-server-2026-01-22.0.log.

When closing the project and reopening, everything works as expected.

Works locally in JVM mode.
