Testing for Catalog/Scaffold URLs is insufficient

[yhakbar]

Describe the bug

Take a look at the issue described here:
#3031

Users occasionally have to suffix go-getter URLs in Catalog/Scaffold with //. in order to have them parsed correctly.

It's likely related to how we're parsing the URLs in the actions.

We should improve test coverage so that users don't hit weird edge cases.

Expected behavior

Users should be able to use any valid go-getter URL for the Catalog and Scaffold commands.
