log the base directory when searching all sub-paths for wc3 exe

[Cokemonkey11]

In the current version of code, the exception here logs all the paths that wc3libs tries, but it doesn't mention the base path that was requested.

For debugging wurstscript/WurstScript#1034, it seems more valuable to see what base path was provided by consumer. It is no longer useful to log the "paths tested" since we know that part to be working.

Looks good to me, just the small changes with using Paths.get.

As @Frotty usually maintains this repo, I would let him do the merge then :)
