.NET Core devfile does not work with ephemeral mode

[amisevsk]

Description:
Issue eclipse-che/che#13739 means that running the .NET devfile in ephemeral mode results in error markers everywhere.

The workaround is currently to dotnet restore and restart the workspace; this does nothing since any changes are not persisted in ephemeral mode.

When running in non-ephemeral mode (and after running the update dependencies task and restarting the workspace), the language server works as expected.

any chance that plugin broker refactoring will address this case?

[amisevsk]

Plugin broker refactoring likely won't have an impact on this, though I can no longer reproduce this on 7.3.2 (likely due to eclipse-che/che-plugin-registry#199).

Currently, the project initially has error markers, and the update dependencies command must be run, but after that I see on issues. I think this one can be closed.

Should be fixed since eclipse-che/che#13739 is closed
