Minify throws TypeError when minifying if with return statement in it.

Describe the bug

Hi everyone, i’m using @babel/core 7.6.0 and babel-minify 0.5.1 and i got TypeError, trying minifying code provided below:

To Reproduce

Minimal code to reproduce the bug

function foo(bar) {
    if (bar) {
        return 'baz';
    }
}

Actual Output

TypeError: unknown: Cannot set property inList of [object Object] which has only a getter
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! ring-react-components@1.12.2 test-minify: `minify ./src/components/ActionsBox.js --outFile mActionBox.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the ring-react-components@1.12.2 test-minify script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

How are you using babel-minify

minify ./src/components/ActionsBox.js --outFile mActionBox.js

Also, can be reproduced in babljs.io: https://babeljs.io/repl/#?babili=true&browsers=&build=&builtIns=false&spec=false&loose=false&code_lz=GYVwdgxgLglg9mABMOcAUAjAhgJwJSIDeAUAJAzCKa4EmL2Kk4CmUIOS2AXgNzEOIAvsUFA&debug=false&forceAllTransforms=false&shippedProposals=false&circleciRepo=&evaluate=false&fileSize=false&timeTravel=false&sourceType=module&lineWrap=false&presets=babili&prettier=false&targets=&version=7.7.1&externalPlugins=

{
  plugins: [],
  presets: []
}

Possible solution

Error is somewhere in babel-plugin-minify-simplify, when i disable this plugin minifying works, but i cant do that for every dependency and i think that minifying should just work for that case.

This started happening to us since yesterday noon. Still digging into any library dependency update that might cause this.

Looks like we got a fix!
