When asking the user for a desktop it is now easy to specify that the
default should be the current desktop.

DEFAULT parameter which specifies the return value when
`desktop-dirname' is `nil', instead of previously an empty string.
(desktop-registry--completing-read): Add optional DEFAULT-CURRENT
parameter which specifies that the current desktop should be the
default when asking for a desktop.
(desktop-registry-remove-desktop): (desktop-registry-rename-desktop):
Use the current desktop as default when asking the user to select a
desktop.
* desktop-registry.el (desktop-registry--canonicalize-dir):
(desktop-registry-current-desktop): New functions.
(desktop-registry-add-directory): Use
`desktop-registry--canonicalize-dir' to get the "clean" directory
name.
- desktop-registry.el (desktop-registry--completing-read):

(desktop-registry-change-desktop): Use
`desktop-registry--completing-read' to interactively ask the user
which desktop to switch to.
