WordPieceTokenizer inconsistent lowercase behavior

[chenmoneygithub]

pretokenize method has lowercase=True by default, while WordPieceTokenizer has lowercase=False by default. The functionality is fine, so this is non-blocking, but shall we make them consistent?

Yeah pretokenize is not exposed so not blocking, but this would be a good one liner to clean up!
