test_cleanUpLinks_pipes: Expect uppercase first letter

The first letter of link targets is capitalized when appropriate for
de:wikipedia.[1] TestCosmeticChanges is perfomed on de:wikipedia.[2]
Therefore it should be expected to have an uppercase letter in this
case which is a method of a sub-class of TestCosmeticChanges.
