extends should be ast.Identifier not LexerIdentifier

[alingse]

when use ptsd

f = open('./tutorial/tutorial.thrift', 'r')                                                                               
tree = Parser().parse(f.read())
print(tree)

to parse apache tutorial thrift https://github.com/apache/thrift/tree/master/tutorial it will print

service Calculator extends <ptsd.lexer.Identifier object at 0x1080d2eb0> {
  void ping()
  ...
}

service.extends is still a LexerIdentifier, not a ast.Identifier (yes, no need to add a Extends Node)
