meta og:site_name generated despite being left blank

[razethion]

I noticed a display issue with some platforms that pull both og:site_name and og:title when the WP site title & tagline are left blank. This happens for services like slack & telegram.

If just the site title is provided, a hyphen is generated and it looks funky. If both site title & tagline are left blank, just a hyphen will be generated. This does not occur when AIOSEO is disabled.

Ideally this needs it's own control, or should be disabled entirely.

You can also see that despite setting a custom homepage setting:

It will still display the wordpress configuration:

Also the separator setting here doesn't control the og:site_title separator.
