[Bug Fix] Properly handle empty Discriminator Tab children

[blindaa121]

Description

This PR addresses a regression bug introduced in #1099 which caused Discriminator Tabs to not render. The bug was caused by an invalid check against empty Discriminator props children.

See #1106 for context.

How Has This Been Tested?

Tested with example spec in original issue and navigating to get-series-list, as well as ensuring that Discriminator tabs are still rendering as expected under our available Discriminator test examples.
