Fix magic numbers linter test results [11]

[bdaase]

At the moment it looks like that magic numbers test does not check for magic numbers. You should try to lint the SLDummyClass03 with the magic numbers test, resulting in one occurrence. But there are definitely way more so it looks like the magic numbers test is not testing for magic numbers...

Magic numbers are quite simple:
"b ifNotEmpty: [b := 'hrm'] " -> There's one magic number ('hrm').
"b ifNotEmpty: [b := 'hello']" -> There's no magic number.
"b ifNotEmpty: [b := 'LarsSeifert']" -> There's one magic number.
b ifNotEmpty: [b := 'Lars Seifert'] -> There's no magic number.
b ifNotEmpty: [b := 3.1415931234] -> There's no magic number.

So it seems to be related to some sort of spelling correction, which also fits to the observation, that magic number does the same as the literal value stuff.

Also, it counts the number of methods that have 'magic values'.

Making the fix proposed in #6 (comment) does also fix the ERROR problem mentioned in this issue, only producing normal results

Since this issue is about the "ERROR" message, I opened issue #23 (Magic Numbers are Numbers and not Strings).
