Search in files breaks with synchronizationcontext is null

[alinmircea]

When you disable the splashscreen (nologo) synchronizationcontext.current will be null during workbench initialization.

As a result posting the search results through sync context, during search and replace will break with object null ( the sync context )

This happens because there was no form created before trying to access the context, so context was not created yet.

Workaround allow splash screen.
