Truncated totals on account summary due to bad regex

Truncated totals on account summary due to bad regex

On the account summary page, OD API was using /\d+?/ to scrape item
totals.  In Javascript, this regular expression matches the minimum
possible match, i.e. one digit, even when the total had more than one
digit.  So, for example, if a patron had 10 items out, the checked out
totals on the account summary page in OD API would show 1 item out.
(The totals at the top right of the page are correct.)

This commit fixes the regex.
