 `Plugin_Upgrader::deactivate_plugin_before_upgrade()` is hooked to the
 `'upgrader_pre_install'` filter by `Plugin_Upgrader::upgrade()`, but it
 doesn't always return a value. This still works because the result of the
 filter is only checked with `is_wp_error()` (in
 `WP_Upgrader::install_package()`). However, it could certainly cause bugs
 for other functions hooked to that filter.
