* README: fix migration copy commands

When the docker-compose up is run the first time the nextcloud
directories are created. When after that the `docker cp` command copies
whole folders they are added as subfolders to the existing folders.

For example, when copying the data folder with
```
docker cp ./data/ nextcloud_app_1:/var/www/html/data
```

afterwards the data folder is in `/var/www/html/data/data`

1. Define your whole Nextcloud infrastructure in a `docker-compose` file and run it with `docker-compose up -d` to get the base installation, volumes and database. Work from there.
2. Restore your database from a mysqldump (nextcloud\_db\_1 is the name of your db container)
```console
docker cp ./database.dmp nextcloud_db_1:/dmp
docker-compose exec db sh -c "mysql -u USER -pPASSWORD nextcloud < /dmp"
docker-compose exec db rm /dmp
```
- To import from a MySQL dump use the following commands
```console
docker cp ./database.dmp nextcloud_db_1:/dmp
docker-compose exec db sh -c "mysql -u USER -pPASSWORD nextcloud < /dmp"
docker-compose exec db rm /dmp
```
- To import from a PostgreSQL dump use to following commands
```console
docker cp ./database.dmp nextcloud_db_1:/dmp
docker-compose exec db sh -c "psql -U USER --set ON_ERROR_STOP=on nextcloud < /dmp"
docker-compose exec db rm /dmp
```
3. Edit your config.php
1. Set database connection
```php
'dbhost' => 'db:3306',
```
- In case of MySQL database
```php
'dbhost' => 'db:3306',
```
- In case of PostgreSQL database
```php
'dbhost' => 'db:5432',
```
2. Make sure you have no configuration for the `apps_paths`. Delete lines like these
```diff

4. Copy your data (nextcloud_app_1 is the name of your Nextcloud container):
```console
docker cp ./data/ nextcloud_app_1:/var/www/html/data
docker cp ./data/ nextcloud_app_1:/var/www/html/
docker-compose exec app chown -R www-data:www-data /var/www/html/data

docker cp ./config/config.php nextcloud_app_1:/var/www/html/config
docker-compose exec app chown -R www-data:www-data /var/www/html/config
```
5. Copy only the custom apps you use (or simply redownload them from the web interface):
```console
docker cp ./apps/ nextcloud_data:/var/www/html/custom_apps
docker cp ./custom_apps/ nextcloud_data:/var/www/html/
docker-compose exec app chown -R www-data:www-data /var/www/html/custom_apps
