Fixes directory paths with slash at the end during "archive_bag".

[sterlingbaldwin]

If the user passes something like "/Users/me/some_directory/" then what happens is that the tar ends up as "/Users/me/some_directory/.tar" instead of ""/Users/me/some_directory.tar" like it should be. This PR is just two lines that remove the trailing os.sep character from the bag_path so that the tar ends up where it should be.

Thanks for reporting this. I fixed it a bit differently in b126a96, but the result should be the same without having to add an additional unit test.

Ah, I didnt see it had been fixed already. Your method is definitely more "pythonic."

I hadn't fixed it prior to you reporting the issue, so definite thanks and credit go to you for catching it!
