Update Babel Transformers mapping

[lgvo]

Some transformers are merged since babel 5.8.2 c0fd4c1f9e0b18231f585c4fa793e4cb0e01aed1

Looks like is not a good suggestion to use only one.

But for now I only have some warning messages:
[BABEL] The transformer es6.parameters.default has been renamed to es6.parameters
[BABEL] The transformer es6.parameters.rest has been renamed to es6.parameters
