React Native's module bundler (aka packager) has its default Babel
preset - react-native/babel-preset - which it uses in the absence of a
custom .babelrc. Unfortunately, the default may be tripped by the
presence of a .babelrc in dependencies. Additionally, if the default
does not get tripped, the npm install of lib-jitsi-meet as a dependency
may fall into a recursion in which Babel attempts to transpile
react-native/babel-preset. To reduce the risks of stumbling upon such
problems, move Babel's configuration inside the Webpack configuration
file.
