Bug 25683: Fix grouping of results

DBIX doesn't seem to work as I expected - if trying to group by we can only
get the columns we grouped by, otherwise the queries are much more complicated
and come out wrong

This patch removes the 'amountoutstanding' from the query. Note that we do return patron
object, however, to access all the columns we must discard_changes (or refetch)

Also fixes a typo 'verbosse'

To test:
1 - charge a $1 fine to a patron
2 - pay off the fine
3 - perl misc/cronjobs/update_patrons_category.pl -f J -t J -fu=5 -v
4 - Note the patron is returned twice
5 - export DBIC_TRACE=1
6 - repeat 3 - view the SQL query and see how odd it is
7 - Apply this patch
8 - repeat 3 - simpler query
9 - patron returned only once
