Fix empty meta fields input in Advanced Settings #78576

Summary

The advanced settings input array input converted an empty field to an array with a single element ['']. This led to the following in Discover:

  1. Remove all metadata

2. Have a look at Discover, there's a unknown field now

image

This PR converts an empty input to an empty array, so this is fixed.

Note: if an advanced setting is already saved with the empty string array, this won't fix it - it has to be manually changed by editing the setting

Fixes #58446

Tested and this LGTM. Note that if an advanced setting is already saved with the empty string array, this won't fix it - it's just about newly edited settings.

I checked current settings of type array and I don't think it's a valid use case to have a single empty string value for them: context:tieBreakerFields, defaultColumns, metaFields, securitySolution:defaultIndex, xpackDashboardMode:roles
