loadUpdateData does not escape apostrophes

We use the loadUpdateData feature with a CSV that contains data like this:

id,key_en,content_en
"1","0100","Please don't do this."

The statement that liquibase generates from this CSV looks like this:

INSERT INTO test (id, key_en, content_en)
VALUES ('1', '0100', 'Please don''t do this.')
ON DUPLICATE KEY UPDATE
key_en='0100', content_en='Please don't do this.'

As you can see, in the update-part of the statement the CSV-string is not escaped appropriately.

We checked the code and it seems that due to the refactoring of the class InsertOrUpdateGeneratorMySQL the escaping part got lost. Maybe the escaping should now take place at the CharType-class (like at the DateTimeType).
