Prior to this commit, translations were built in the serializers. This could not work as a single translation can be used for different source messages having different placeholder content. Serializers do not try to replace the placeholders any more. Placeholders are replaced by the translation bundle and the source message is given as parameter so that the content of the placeholders is taken into account. Also XMB ids are now independent of the expression which is replaced by a placeholder in the extracted file. fixes #12512
