### What?
When a user lands on an edit page that has a relationship to an `Upload`
field (which is `HasMany`). The UI will make a request with `limit=0` to
the backend providing there is no IDs populated already.
When a media collection is large, it will try and load all media items
into memory which causes OOM crashes.
### Why?
Fixes: https://github.com/payloadcms/payload/issues/11655 causing OOM
issues.
### How?
Adding guard check on the `populate` to ensure that it doesn't make a
request if not needed.
