Summary:                    Cannot restore from another SD using same Media
Type.
Description: 
In our setup we have 1 director, 2 storage daemons and 2 file daemon.

Director is named : moinecopix.dom_bureau01-dir
Storage 1 is named : moinecopix.dom_bureau01-sd
Storage 2 is named : duplicatix.dom_bureau01-sd

SD-1 and SD-2 have one Device each, that is a LTO-3 tape drive. They also have
the same Media Type defined (LTO3).

SD-1 is used for backups, and SD-2 is only used for restore.

Setup was working fine in 2.2, we where able to restore file from tapes mounted
in SD-2.

Since upgrade to 5.0.3, this is not working anymore. When selecting another
storage than SD-1 in restore jobs leads to errors.

When asked on mailing list, no one could tell me if that's a bug or not :
http://www.mail-archive.com/bacula-users@lists.sourceforge.net/msg45567.html

I have the feeling that is a bug because :
- The documentation seems to say that it should be possible : "For example, if
you specify a Media Type of "DDS-4" then during the restore, Bacula will be able
to choose any Storage Daemon that handles "DDS-4"."
- The wizard let me choose another storage daemon for restore. If restore is
only possible from SD-1, i think it should not let me change the storage daemon
used.
- Same setup was working in 2.2.x

Steps to Reproduce: 
- Launch restore wizard in bconsole

- Folow the wizard and at the end, choose "mod" option to change the storage
daemon used for restore.

- Job is canceled and get errors in logs

Additional Information: 
This is the error we get in the logs :

Sorry you have problems with Bacula, but what you are trying to do is
unsupported. This is written in the manual in the Storage section, perhaps it
can be more clear, so feel free to submit a documentation patch.

"Thus you should probably use the same Media Type specification for all drives
where the Media can be freely interchanged. This is not generally an issue if
you have a single Storage daemon, but it is with multiple Storage daemons,
especially if they have incompatible media"
