Two test cases are added: `testFutureUnsupportedMetadataVersion()` and
`testCorruptedMetadataFile()`.
Test first one is the test case for the future unsupported versions that is
not in the MetadataVersion.SUPPORTED_VERSIONS list. In test case `v4` is used
for now (since the last version is `v3_1`). There was `JsonMappingException`
earlier.
Other test case uses metadata file with corrupted json part. There was
`JsonParseException` earlier.
Note: To avoid any `json` deserializing exception we catch
`JsonProcessingException` (parent class of the above ones).
