sstableloader --ignore-missing-columns does not handle multiple columns.

[elcallio]

Because the command line parser does API is confusing and the originating programmer (me) is stupid.

I ran the test with this fix, but the test still fails with same error:

Test scenario to reproduce:

1. CREATE KEYSPACE ks WITH replication={'class':'SimpleStrategy', 'replication_factor':1}
2. CREATE COLUMNFAMILY cf (key int, c1 text, c2 text, c3 text, PRIMARY KEY(key, c1))
3. Insert 10 rows
4. DROP TABLE cf
5. CREATE COLUMNFAMILY cf (key int, c1 text, PRIMARY KEY(key, c1))
6. Run sstableloader:

@elcallio could you please take a look on this?

The above example works perfectly fine for me with 8080009 applied. Is this still an issue, not just branches not updated?

Reopening because of the same problem as in https://github.com/scylladb/scylla-tools-java/issues/216#issuecomment-2297045852. Closing the issue activated some broken dtests and broke CI.
