This PR fixes several bugs in setting storage

* The default STORAGE_TYPE should be the provided type.
* The Storage config should be passed in to NewStorage as a pointer - otherwise the Mappable interface function MapTo will not be found
* There was a bug in the MapTo function.

Fix #13286

Unfortunately there was a mistake in #13164 which fails to handle
os.PathError wrapping an os.ErrNotExist

* The `.Use` of storageHandler before setting up the template renderer
causes a panic if there is an error to log.
* The error passed to `ctx.Error` in that case may contain sensitive
information and should not be rendered to the end user. We should
instead log the error and render a simple error message.
* There is no handling of missing avatars and this needs a 404. Minio
errors need to be mapped to standard golang errors such as
os.ErrNotExist.
* There is no logging when storage is set up.
