Add more & better logging to test cases

[adityarao2005]

Add more logging for test cases.

Also make sure its proper logging in which it's results get exported so viewers can check their logs for the GH Action that they ran.

We can do something like this:

#ifdef WEBCRAFT_BUILD_TESTS 
#define WEBCRAFT_INTERNAL_DEBUG_TRACE_LOG(str, ...) // some logging format either use fmt or iostream for this ... doens't matter as this is for test case stuff
#else
#define WEBCRAFT_INTERNAL_DEBUG_TRACE_LOG(str, ...)
#endif
