Empty searchable array is indexed with only meta data.

[wisoot]

Similar to the bug report in scout here: #350 - if meta data is not empty due to the setting to switch on soft_delete in scout.config.soft_delete.

In this line here: https://github.com/algolia/scout-extended/blob/v1.6.0/src/Jobs/UpdateJob.php#L109 checking on emptiness of searchable array should be perform separately from metadata as it will always be fault when soft_delete is enabled.
