Bug 20697: Bind calling GetAnalyticsCount to pref EasyAnalyticalRecords

Bug 20697: Bind calling GetAnalyticsCount to pref EasyAnalyticalRecords

If you do not use the EasyAnalyticalRecords feature (introduced with
bug 5528), you will have a lot of warnings in zebra-output.log like:

zebrasrv(1096) [request] Search biblios ERROR 114 1 1+0 RPN @attrset Bib-1 @attr 1=8911 259186

They come from C4::Items::GetAnalyticsCount called by catalogue/detail.pl.
This sub starts a Zebra search on index 'hi' (Host-Item-Number).
If you do not use this field at all (related to 773$9 in MARC21), Zebra
returns an Unsupported Use attribute error (114).

In making this change, I added one minor change:
[1] Remove the commented GetAnalyticsCount in additem.pl and correcting
    indentation in that loop (removing tabs). So no change at all there.

NOTE: I will propose to bind the GetHostItemsInfo call in detail.pl and two
other scripts to this preference too on report 20702.

Test plan:
[1] If you use EasyAnalytics, verify that there is no change.
[2] If you do not, check the zebra-output.log. You should no longer see
    searches for Host-Item-Number with 1=8911. (As well as ERROR 114 on
    this index.)
