mq: remove leading slash from url when qimporting

When trying to qimport a url that ends with a slash
os.path.basename would return an empty string. So
when seeing a leading slash, remove it and infer the
patch name from the remaining url.

e.g. `hg qimport http://paste.pocoo.org/raw/xxx/`
deduced '.' to be the patch name. Now we'll deduce 'xxx'.

We could probably remove all leading slashes but this
is the more common case.
