>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Ivan Gagarkin

> *Steps to Reproduce:*
>  # Create a table using the command: {{{}CREATE TABLE TEST (id INT PRIMARY KEY, country VARCHAR){}}}.
>  # Create a POJO with corresponding fields to the table.
>  # Create a Key-Value (KV) view: {{{}KeyValueView<Integer, Country> countryValueView = table.keyValueView(Mapper.of(Integer.class), Mapper.of(Country.class));{}}}.
>  # Insert some data into the table.
>  # Alter the table by adding a new column: {{{}ALTER TABLE TEST ADD COLUMN city VARCHAR{}}}.
>  # Create a new POJO to accommodate the added column.
>  # Create a new KV view: {{{}KeyValueView<Integer, CountryCity> countryCityKeyValueView = CLUSTER.node(0).tables().table(TABLE_NAME).keyValueView(Mapper.of(Integer.class), Mapper.of(CountryCity.class));{}}}.
>  # Attempt to remove data from the table using the first KV view: {{{}assertTrue(countryValueView.remove(null, 0, valuePojo));{}}}. This fails with the error "No mapped object field found for column 'CITY'".
>  # Try to remove data using the second KV view: {{{}assertTrue(countryCityKeyValueView.remove(null, 0, new CountryCity(valuePojo.country(), null)));{}}}. This returns {{{}false{}}}.
> *Expected Behavior:*
>  ** It should be possible to remove values using either of the KV views after altering the table structure.
> *Actual Behavior:*
>  ** Unable to remove values using the first KV view due to the lack of a 'city' column in the original POJO.
>  ** Unable to remove values using the second KV view as the {{equals}} method does not function as expected.
