JCLOUDS-930: LocalStore -- fixup for prefixes.
When filtering results, we have to consider that a result was added to
the common prefixes list in its entirety (i.e. a directory). Such
results should be filtered out from the delimiter test.
An example that demonstrates this problem is if one creates a
directory "foo" and an object within it called "file". When listing
the results, they will include the directory object "foo" and the
object under "foo/file". During a non-recursive listing, we create a
list of common prefixes ("foo"). Subsequently, jclouds should remove
all objects that include the delimiter ("/"), however, that would not
apply to "foo". With the change to include the delimiter in the
listing, we need to be careful not to return two values "foo" and
"foo/".
A unit test for the local blob store to highlight this problem is
included. An integration test "testDirectory" also catches this issue.

> Currently, the blob store interface exposes an _inDirectory()_ method to set
> the directory from which to list blobs. This is implemented through a
> combination of prefix and delimiter options, namely combining them to
> retrieve all objects nested under a specific "directory" (e.g. dir/).
> jclouds should expose an explicit prefix option to, for example, allow
> listing objects that all start with a common name. The difference from the
> existing inDirectory() option is that the prefix would not require the
> delimiter to be set and could be an arbitrary string.
> The prefix is an option supported by S3, Swift, Azure, and Google Cloud
> Storage.
