Approve current output and fix the approval test reporter

Approved the 30 day fixture output as-is so there is a baseline before
refactoring. Conjured Mana Cake is still wrong here, that changes later.

The approval test was also crashing with "no reporter configuration"
instead of showing a diff. pytest-approvaltests 0.2.4 doesn't work with
approvaltests 19, so pass PythonNativeReporter directly.
