[dependabot-preview]

Bumps fs-extra from 4.0.3 to 5.0.0.

Changelog

Sourced from fs-extra's changelog.

5.0.0 / 2017-12-11

Significant refactor of copy() & copySync(), including breaking changes. No changes to other functions in this release.

Huge thanks to [manidlou](https://github.com/manidlou) for doing most of the work on this release.

• The filter option can no longer be a RegExp (must be a function). This was deprecated since fs-extra v1.0.0. #512
• copy()'s filter option can now be a function that returns a Promise. #518
• copy() & copySync() now use fs.copyFile()/fs.copyFileSync() in environments that support it (currently Node 8.5.0+). Older Node versions still get the old implementation. #505
• Don't allow copying a directory into itself. #83
• Handle copying between identical files. #198
• Error out when copying an empty folder to a path that already exists. #464
• Don't create dest's parent if the filter function aborts the copy() operation. #517
• Fix writeStream not being closed if there was an error in copy(). #516
