Adding "fetch all versions" back (waldophotos#57)

* Adding "fetch all versions" back

When the feature that allows refresh rate was released, the `_checkForAllVersion` method was removed (https://github.com/waldophotos/kafka-avro/pull/42/files#diff-f1df90835d08fdef1a9efce902948d9fL99).

This PR adds back this behavior. Thanks @manikawnth-abg

Fixes waldophotos#56
