Bug 17679: C4::Circulation - Remove unused GetItemIssues

Bug 17679: C4::Circulation - Remove unused GetItemIssues

Ready for an archaeology course?

C4::Circulation::GetItemIssues is only used once, from
catalogue/issuehistory.pl
This call has been added by
  commit 95d6452462a560ba0c0ac859a2cfb7783c25c925
    Adding some more information on issuehistory.
which says "Adding itemnumber to issuehistory.pl API so that one could search
for issuehistory of a specific item."
So it added the ability to see the item issue history but did not
provide a way to access it via the interface.
It's ok so far but this subroutine is broken since
  commit aa114f53499b9cffde0571fe7e08622f9c9a332a
    Bug 5549 : Only use DateTime for issues table
because of this change:
-    my $today = C4::Dates->today('iso');
+    my $today = DateTime->now( time_zome => C4::Context->tz);

I let you catch the typo ;)
And since this commit the subroutine explodes with "The following
parameter was passed in the call to DateTime::from_epoch but was not
listed in the validation options: time_zome"

Since it has never been raised by someone and that the feature is
hidden, I'd recommend to simply remove it.

Note that the "Checked out from" column would have been wrong even if we
fixed all the previous issue.

Test plan:
Just dig into the code and confirm what this commit message tells
