Fixes bug 1202415 __repr__ was added to APIResourceWrapper in the recent commit, but it searches all attributes in _attrs list. When an attribute defined in _attrs actually does not exist, __repr__() fails. This commit changes __repr__ to ignore non-existing attributes. Change-Id: Iebaeae78f3763d87f3993ba5c4bbed4c23e84c45
