Always update the git submodules

Project Tester is still failing with:

+ [ ! -d stdx-allocator ]
+ cd test
+ ./run_tests.sh
find: ‘../stdx-allocator/source’: No such file or directory
Compiling unit tests...../src/dparse/parser.d(9): Error: module `mallocator` is in file 'stdx/allocator/mallocator.d' which cannot be read

So I assume this is due to the directory being existent, but being empty.
