Summary:                    ExternalProject UPDATE_DISCONNECTED does not work
with custom UPDATE_COMMAND
Description: 
This CMakeLists.txt file:
  CMAKE_MINIMUM_REQUIRED(VERSION 3.1)
  PROJECT(test NONE)
  INCLUDE(ExternalProject)
  SET_PROPERTY(DIRECTORY PROPERTY EP_UPDATE_DISCONNECTED 1)
  ExternalProject_Add(sf GIT_REPOSITORY
"https://github.com/sharemind-sdk/vm_m4.git" UPDATE_COMMAND ${CMAKE_COMMAND} -E
echo "Hello, World!")

yields in the following `make`output:
  Scanning dependencies of target sf
  [ 14%] Creating directories for 'sf'
  [ 28%] Performing download step (git clone) for 'sf'
  Cloning into 'sf'...
  Already on 'master'
  Your branch is up-to-date with 'origin/master'.
  [ 42%] No patch step for 'sf'
  make[2]: *** No rule to make target 'sf-prefix/src/sf-stamp/sf-skip-update',
needed by 'sf-prefix/src/sf-stamp/sf-configure'.  Stop.
  CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/sf.dir/all' failed
  make[1]: *** [CMakeFiles/sf.dir/all] Error 2
  Makefile:83: recipe for target 'all' failed
  make: *** [all] Error 2

Same error with UPDATE_DISCONNECTED set on the external project itself.

Additional Information: 
Tested with cmake-3.3.2 and cmake-3.4.1.
