Fix master-only regression on saving event info when no custom data applies

Overview

Fix master-only regression on saving event info when no custom data applies

Before

Event Info not saving when there are no custom fields extending event

After

now it does

Technical Details

I didn't see this before as I had a tonne of custom data locally but after re-building my site I hit it

I'm pretty sure this is the same issue as @demeritcowboy reported in https://lab.civicrm.org/dev/core/-/issues/4968
and the reason why I couldn't replicate that would have been the same
