[xbuild] Reset ConsoleLogger when a build finishes.

MSBuild hosts like monodevelop, which use the same logger
for multiple builds, get errors/warnings from older builds.
So, reset them whenever the BuildFinished event is raised.

ILogger.Shutdown () is invoked when the host is about to quit,
according to msdn, so can't use that.
