ID Management: Add some basic tests regarding name handling.
Those tests are here mostsly to ensure ID name management is working as expected (the code ensuring we never have two ilocal data-blocks of the same type with the same name in a .blend file). Note: Currently fails in some cases, fixes are incoming. Note: Ideally this would be in C, but we already have too many tests linking the whole Blender and its libraries, this is becoming a real pain to link debug + ASAN + tests build these days... So until we find a better way to handle those dependencies, sticking to simple python scripts.
