Jonathan Hefner 9495a340b9 Avoid testing Thor internals
Thor's `apply` method is responsible for fetching a template when given
a URL.  Therefore, assume that `apply` behaves correctly, and simply
test that `apply` is called correctly.

This avoids errors like https://buildkite.com/rails/rails/builds/74245#540ecdf1-58ea-470a-a397-09f675520eb9/1100-1109
