Fix AST-137779: Guard against null getResults() in cxProjectMatchesWorkspaceProject

Results.getResults() can return null when no results have been loaded yet
(e.g. fresh IDE session before any scan is imported). The prior check only
guarded against a null Results object, causing an NPE on the first click
of the Start Scan button and preventing scans from running.
