fix(restore-util): consider long and short names when restoring platforms from package.json

[breautek]

Platforms affected

All

Motivation and Context

Fixes #878

Description

Try platform name prefixed with cordova- for platform / spec mapping, before falling back to plain platform name.

Testing

Added a unit test to ensure that platforms are restored without config.xml engine entry, and from devDependency. All existing unit tests passes.

Manually tested in a repo project.

Checklist

• [x] I've run the tests to see all new and existing tests pass

Not sure if this is a safe assumption though.

Do we support custom platforms...? If so, then this PR would probably break custom platform restorations...

I believe we always supported custom platforms, even though I am not sure if any exist.
