When restoring a Koha instance, and the database user does not exist, an error is shown,
although it is prevented from stopping the script by ` || true`. This patch removes the
` || true` guard, and rather uses `DROP USER IF EXISTS` which does exactly what one
would expect, without confusing error messages, whether the user existed or not.
To test:
1) Assume your Koha instance is called `asdf`.
1) Export the Koha instance using `koha-dump`.
2) Remove the instance completely using `koha-remove`.
3) Import it again using `koha-restore`.
4) No error should be shown, and the import should work. There was NO user to drop, therefore `DROP USER IF EXISTS` did nothing.
5) A database user called `koha_asdf` should exist, and have all privileges on the database of the same name.
6) Remove the instance again using `koha-remove`.
7) Now create a database user in MySQL called `koha_instance` where instance is the name of your dumped koha instance.
8) Import your koha instance again using `koha-restore`.
9) Again, no error should be shown, and the import should work. There WAS a user to drop, therefore `DROP USER IF EXISTS` dropped the user before creating a new one.
10) Again, a database user called `koha_asdf` should exist, and have all privileges on the database of the same name.
