#406 When serveral disk share the same cddb key, only the latest is usable, buttons are not active

[Solbu]

Relaying a bug repport from «Chris» who was unable to create a ticket for some reason.

===
When an entry in *CDDB returns multiple records (i.e
several disks share the same key), only the lattest is shown in GRIP.

Impossible to switch between records with arrows buttons on the first
pannel, only the lattest is shown and if this is definitively not the
right one... unusable.

This prevent ripping of many CD (event recent), since their code has
been already reused by another production.

Distro: F29 x64
GRIP: 3.9.0 from distro
Params: untouched from install, same result when tweaked

Exemple entry: key b10c5e0c shared by "Shaka Ponk / Shaka Ponk" and
"Sharon Knight / Sharon Knight".

Edit: when asking for a manual diskdb scan, the "Shaka Ponk" content is
quickly displayed and immediately replaced by the "Sharon Knight"
content, without any possible change.

Regards,
Chris.
