[Ide] Refresh type system for all projects when editorconfig added

If Configure and Suppress issues is used when the solution has
multiple projects the updated analyzer setting in the added
editorconfig file was not applied to all projects.

To fix this when the ApplyAnalyzerConfigDocumentAdded method is
called for the Roslyn workspace the project info is refreshed in
the type system.

Currently there is some odd behaviour here. The .editorconfig file
does not always get added as a link to the current project. The
ApplyAnalyzerConfigDocumentAdded method is only called once for
a single project.

Also handle any errors when an .editorconfig file is removed and
the associated document id is not in the workspace.
