Upgrading @babel/runtime to 7.0.0-beta.56 breaks the build

[vladholubiev]

What I tried:

• Installing @babel/runtime-corejs2
• Adding custom babelrc with this: { "plugins": [ "@babel/plugin-transform-runtime", { "corejs": 2 } ] }
• Installing @babel/plugin-transform-runtime with @babel/core and pinning them to 7.0.0-beta.56

But didn't change the situation.

I will need to fix this when I update everything to 7.0.0-beta.56. In the meantime, you might want to stay on beta.55. The good news is that Babel 7 seems very close to its first release candidate!

Babel 7 is out 🎉
