Remove useless auto_generated param from PlaylistVideo#to_xml

given the variables available in this function's context, 'author' and 'ucid'
provide the same data 'self.author' and 'self.ucid', respectively.

Given that fact, the variable `auto_generated` has no impact on the logic of
this function, and hence can be safely removed. this greatly simplifies the
code and makes it perfectly compatible with crystal's calling convention for
'#to_xml' methods.
