Ensure slashes and UTF-8 characters stay unescaped

[fredden]

This pull request ensures that slashes and UTF-8 strings are always unescaped in composer.json. The underlying formatting tool correctly detects if the source file already has escaped slashes and/or escaped UTF-8 characters and produces output to match this. However, as seen in #965, this is not always expected behaviour. This pull request applies an opinionated stance to ensure that formatting remains consistent across projects.

Note that the underlying library that does formatting detection is working correctly.

Fixes #965

Closing in favour of #1056.

[fredden]

@localheinz I'm happy to rebase these changes and make them work with the latest version if you'd like. I'll hold off doing that for now though, as GitHub will orphan the branch from this pull request if I force-push while the pull request is closed (and I don't have sufficient permission here to re-open this pull request).
