Flyway 8.1.0 with SQL Server fails in native with NullPointerException

[jsmrcka]

Describe the bug

Flyway 8.1.0 together with SQL Server fails on native application startup, throwing a NPE due to a missing resource:

org/flywaydb/database/version.txt

POM dependencies sample:

    ...
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-flyway</artifactId>
    </dependency>
    <dependency>
      <groupId>org.flywaydb</groupId>
      <artifactId>flyway-sqlserver</artifactId>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-jdbc-mssql</artifactId>
    </dependency>
    ...

Workaround: explicitly include the missing resource in application.properties:

quarkus.native.resources.includes=org/flywaydb/database/version.txt

Expected behavior

No NullPointerException on startup.
