Fixed issue with use of delimiter in container queries.

Currently if you have a container with objects named
x/y and x0 and you use delimiter=/ in your query, x0
will be excluded from the results. This patch resolves
this problem.

To replicate the original issue, create a container
called 'test' with the following objects:

x/y
x0
x1

Then do a GET with 'accnt/test?delimiter=/' and the
following is returned:

x/
x1

i.e. x0 is missing from output.
