Remove setTableName method on User mapper

[adamlundrigan]

Should be replaced by a constructor argument instead? AFAIK there isn't a good use case for being able to change the table name after the mapper is constructed.

This would have to be targed to v2.0 as it's a BC break to remove the setter.
