nixos/nextcloud: fixup #119638

A few minor changes to get #119638 - nextcloud: add option to set
datadir and extensions - ready:

* `cfg.datadir` now gets `cfg.home` as default to make the type
  non-nullable.
* Enhanced the `basic` test to check the behavior with a custom datadir
  that's not `/var/lib/nextcloud`.
* Fix hashes for apps in option example.
* Simplify if/else for `appstoreenable` in override config.
* Simplify a few `mapAttrsToList`-expressions in
  `nextcloud-setup.service`.
