Fixed old import from class-transformer (#56)

* Fixed old import from class-transformer

Since class-transformer@0.3.2 the `class-transformer/metadata/MetadataStorage` got moved to `class-transformer/types/MetadataStorage`.
https://uiwjs.github.io/npm-unpkg/#/pkg/class-transformer@0.3.1
https://uiwjs.github.io/npm-unpkg/#/pkg/class-transformer@0.3.2

* Pinned class-transformer to 0.3.2 (latest)

Some package managers do stupid stuff.

* Pinned it to a version that works

* Switched back to the old input

* Added previously known-good versions
