APPVEYOR_SAVE_CACHE_ON_ERROR=true not working (no caching on failed builds on MacOS)

[GitMensch]

That should be reproducible in any definition, but find a reproducer attached.
The global setting of APPVEYOR_SAVE_CACHE_ON_ERROR does not work, the (expected) local export didn't work either.

A failing build does trigger the artifacts, but not the caching.
The main issue in this environment is that it is ultra slow, with the brew part taking over one hour, so the idea was to split it (manually installing the dependencies) and update the cache with multiple iterations - to get to the real build (which takes 10-20 minutes with all testing).

Apart from the issue that the cache - even with this setting - is only updated on finished builds: isn't there a command to tell appveyor to "update the cache now"? This would solve the issue (and even allow me to put this in several places for the initial cache building).
