Bug 10642: fix inappropriate uses of $sth->finish() in C4::RotatingCollections.pm

From the man page

finish()
Indicate that no more data will be fetched from this statement handle
before it is either executed again or destroyed.
You almost certainly do not need to call this method.

Adding calls to "finish" after loop that fetches all rows is a common
mistake, don't do it, it can mask genuine problems like uncaught fetch errors.

To test:

Verify that prove -v t/db_dependent/RotatingCollections.t passes
