Title: Optimize autoload prefix in composer.json

By having more specific autoload prefixes it is possible to reduce the
number of stat calls made. Also it prevents conflicts with similar
namespaces.

See ref: https://github.com/zendframework/zf2/commit/e58c6cdbf50dd06b71e76a413fb870c95ab22bf5

SessionHandlerInterface is left intentionally.
