[ASTImporter] Propagate error from ImportDeclContext
Summary:
During analysis of one project we failed to import one
CXXDestructorDecl. But since we did not propagate the error in
importDeclContext we had a CXXRecordDecl without a destructor. Then the
analyzer engine had a CallEvent where the nonexistent dtor was requested
(crash).
Solution is to propagate the errors we have during importing a
DeclContext.
