[mu bug] `mu init` doesn't create `~/.cache/mu/xapian` anymore

[tsdh]

Describe the bug

It seems mu init stopped creating ~/.cache/mu/xapian itself at some point. I'm on the current master branch.

To Reproduce

I use this script to initialize mu on new machines or after schema updates:

#!/bin/sh

if [ ! -d ~/.mail/ ]; then
    echo "There is no ~/.mail/ directory."
    exit 128
fi

rm -rf ~/.cache/mu/
# FIXME: Why do I need to do this myself?  I didn't have to do this last time I ran the script.
mkdir -p ~/.cache/mu/xapian
mu init --maildir ~/.mail --my-address=...
mu index
echo "Done!"

Environment GNU/Linux with mu master (da02a954).

Checklist

• [X] you are running either the latest 1.6.x release, or a 1.7.x development release (otherwise, please upgrade). Well, actually a 1.9 dev release. I guess you need to update the template.
