[BUG] Metro still can't build on windows

See original GitHub issue

Repro: Just build RNTester on windows. Related issue: https://github.com/facebook/react-native/issues/20353, https://github.com/facebook/metro/issues/181. From what I test, 0.42.1 works. But not 0.42.2, 0.43.1. 0.43.2., 0.43.3. You can also see the appveyor build log: https://ci.appveyor.com/project/gengjiawen/react-native/build/1.0.22/job/it491en7tm6r69cq.

We’ve just published Metro v0.43.4 which should fix the windows issues: https://github.com/facebook/metro/releases/tag/v0.43.4

Thanks for the information @gengjiawen !

This means that we reintroduced the issue in one of the following commits: https://github.com/facebook/metro/compare/v0.42.1...v0.42.2

@pvdz The most probable thing that can be causing this issue is the upgrade to babel7-beta.54 + the revert of the windows dir normalization.

@gengjiawen can you test if v0.43.3 + a revert of https://github.com/facebook/metro/commit/0b70c9a5db55deb1bd21add57972d66c20c25e2e fixes the issue? if not can test it tomorrow (I’m in European time)
