Get last element as a table name from a topic name

[IlyaTsoi]

It would be better if it didn't depend on the hard-coded ..

template

DId you come across a bug for this, all the debezium connectors create topics in the following format.

<topicPrefix>.<schemaName>.<tableName>

Would be better to return a NULL table name instead of extracting a wrong table name and writing data to it.

In any case a table name is located at the end of the topic name. Isn't it? Current logic brakes when using topic.prefix in debezium config and we get null instead of table name. Of course topic2table mapping by regex will resolve this issue. My solution migth be used as workaround.

@subkanthi one more argument): when getTableNameFromTopic() returns null the table with this name will be created and the table will contain all columns from all source tables). Of course, replication will fail. I have not inspected why, but seen such behavior.
