Duracloud: Space path is optional

refs #7133
Duracloud: Browse works without leading /

refs #7133

Browse resources should only join with the Space/Location path if it does
not contain the Space/Location path already.  Some calls to browse contain
the full path, and others relative paths.  This should work for Spaces with
or without a leading / in the path.

Update directory browser JS in SS to handle paths that don't begin with / as
well.
Duracloud: Minor fixes

Don't display password, show the space path as <None> if it doesn't
exist.
Migrations: Fix to upgrade from 0.4.0 migration

Fix 0004_v0_4_0 migration to match what's in the stable/0.4.0 branch.

Space: post move from munges paths

Update post_move_from_storage_service to pass the same paths into it as
move_from_storage_service.  Because some path munging is done now,
handle if one or both of the paths passed are None.
Space: Move deleted staging copy to post-move function

Move deleting the staging copy to after the protocol specific post
move has run, in case it is needed by the child space. Delete stubbed
functions that were going to do this.
