Queries in import.sql can't be split to multiple lines anymore

[jmartisk]

With the latest snapshot (019f4e7e63; it doesn't happen in 1.7.0), I noticed that if I have queries in my import.sql that are split into multiple lines like

insert into Person (gender, name, id)
values ('MALE', 'Jimbo', nextval('hibernate_sequence'));

Then each line is executed as if it were a full query, and the application breaks in this case.
For preserving readability, we should keep allowing splitting queries into multiple lines.

@Sanne looks like your patch didn't work as expected?

I think the issue is there: https://github.com/quarkusio/quarkus/pull/11353/files#diff-62f3a6c6771d8f3a4819eb119de072ecR12 .

The INSTANCE should be an instance of QuarkusImportSqlCommandExtractorInitiator.

Let me work on a patch (and add a test).
