BUG: ExtensionBuildSystemTest: Improve tests robustness

This commit updates the configuration of py_cmake_slicer_extensions_index_build_*
tests to ensure the env. variable SLICER_EXTENSION_MANAGER_SKIP_MIDAS_UPLOAD
is ignored. It ensures that test will pass on system when midas client is
not used.
