Wrong repository config path is resolved when a manual backup is done (info.magnolia.module.backup.app.BackupPresenter.manualBackup())

BackupOperationConfiguration configuration = backupOperationConfiguration()
                        .withBackupLocation(Paths.get(items.get(BackupView.FORM_VIEW_MANUAL_BACKUP).getItemProperty("backupPath").getValue().toString()))
                        .withRepositoryPath(Paths.get(properties.getProperty("magnolia.repositories.home"), "magnolia"))
                        .withConfigurationPath(Paths.get(properties.getProperty("magnolia.home"), properties.getProperty("magnolia.repositories.jackrabbit.config")))
                        .build();

Here magnolia.home is used to compose the path in addition to magnolia.repositories.jackrabbit.config. magnolia.home can be configured in magnolia properties, so it might lead to errors locating this configuration file.

I guess that it should be resolved as it is done in provider implementation for Apache JackRabbit JCR repository (info.magnolia.jackrabbit.ProviderImpl) where info.magnolia.cms.core.FileSystemHelper.getAbsoluteFileSystemPath(String) is used to compose the path, getting absolute filesystem path and adding application root if path is not absolute.

Same for: info.magnolia.module.backup.commands.BackupCommand.executeAutomatedBackup(Context, String)
