[RETEST] KotlinX vs AvroJavaGen incompatibility

[zambrovski]

I did the following:

• created some events in Axon Server event store using KotlinX events
• Switched to Avro Java Events (without resetting event store) by changing Maven Profile

Since I now had the generated Java classes on the classpath I could only register them.
The projections started to replay and failed because the fingerprint was not found.

I assume it is correct - the fingerprint is different, but I thought that I designed the hand-written KotlinX serializable events at least reader-compatible to the schema of the events generated in Java.

@jangalinski let's double-check why we get an unknown fingerprint (error from avroSchemaResolver) instead of a loaded (reader-compatible class).
