Linter tests not listed in linter result screen

[bdaase]

The results of some linter tests seem not be to be listed in the result screen of the linter. Especially the tests "Class variable capitalization" (line 14), "Instance variable capitalization" (l. 22), "No class comment" (l. 72), "Variables not referenced" (l. 86) and "Has class instance variables but no initialize method" (l. 13) seem to be affected.
(At least) they share the attribute that they do not have the basic returnClass for the result, their types are either RBClassEnviroment or RBVariableEnviroment,
