Short-circuit get_output_dicts_from_metadata's if clause for faster evaluation

[kenodegard]

Description

Reorders if-clause to run cheaper (faster) calculation first and more expensive calculation second so we can benefit from short-circuiting.

Split from:

• Miscellaneous render speedups #5225
• Speed up rendering by avoiding costly/redundant function calls #5248
• Remove duplicate extract_package_and_build_text call #5253

Checklist - did you ...

• Add a file to the news directory (using the template) for the next release's release notes?
• Add / update necessary tests?
• Add / update outdated documentation?
