[shlwapi] Add NULL checks to StrCpyW and StrCatW

Hello friends,
according to these results, it looks like the test I added in the patch 
crashes win2k SP4 but it works on all others. And it does not seem to be a 
thing that it can be resolved with dynamic library loading.
So, what should I do?
Do I need to comment them like it has been done (for example) into 
test_StrChrA()?
Do I need to remove interely the test and revive previous patch?
Please excuse my inexperience...

Sincerely,

Carlo Bramini.
