Fix openstudio_utilities_tests link issue

@macumber The CMake macro CREATE_TEST_TARGETS had the target link libraries ordered with gtest and gtest_main before the thread library, and on Ubuntu 14.04 this was causing the link to fail for openstudio_utilities_tests. Moving ALL_DEPENDENCIES to after gtest and gtest_main fixes that. Also, the thread library was showing up twice in the link command, so I commented out the explicit addition for the utilities test. I've left it in as a comment since I can only build this branch on Ubuntu and it needs to be verified on other platforms.
