Bug 5882 : catalogue/moredetails (minor) changes

MT3288 moredetail.tmpl Lost and Damaged first choice is empty

    First choice was the first value of the authorised value list
    This is not handy for users.
    Rather than showing the first value, inserting a new empty value for users to see what to do

Term "Total Renewals" misleading, change to "Current Renewals"

    In koha-tmpl/intranet-tmpl/prog/en/modules/catalogue/moredetail.tmpl under History,
    there's a Total Renewals entry: seems to indicate a cumulative count of renewals on
    the item, which it is not, contrary to "Total Issues" just below.
    Moved the line up outside "history", and renamed it "Current Renewals".
