Bug 7825: (follow-up) fix the force value for the bootstrap theme

If the pref was set to 'force', the item selection was not shown.
.copiesrow should be hidden before showing specific #copiesrow_ID

Passes all tests and QA script.

Works on template level, tested with Boostrap and Prog theme
with all 3 possible seetings of OPACItemHolds:

1) no = offer only title level holds
2) yes = offer both title and item level holds
3) force = offer only item level holds

Also ran some additional tests on the Boostrap theme with
deactivated Javascript.

Note: I like this, but I think when "force" is selected the
item list needs to be shown by default. I am also not happy about
preselecting the first item.
