[PATCH v3 6/9] http-push: Normalise directory names when pushing to some WebDAV servers

[Tay Ray Chuan <rctay89@gmail.com>]

Fix a bug when pushing to WebDAV servers which do not use a trailing
slash for collection names. The previous implementation fails to see
that the requested resource "refs/" is the same resource as "refs"
and loads every reference twice (once for refs/ and once for refs).

This implementation normalises every collection name by appending a
trailing slash if necessary.

This can be tested with old versions of Apache (such as the WebDAV
server of GMX, Apache 2.0.63).
