Problems when using babel plugins

[ksolomykinvirtru]

In current version of istanbul-lib-instrument ("^1.7.3") Instrumenter class method _createClass does not take into account babel plugins which being used in our project. This method only uses hardcoded list of plugins.
In version 3.0.0 this problem was resolved. Please, update version of istanbul-lib-instrument package to 3.0.0 in your package.json.
