Removing static access on DefaultLogger from non static member function
Removing static access on DefaultLogger from non static member function

The member function setLogLevel called the DefaultLogger which was a
static member of the logger class. It works in case the DefaultLogger has
been initialized. In case this the DefaultLogger is not used, this leads
to a null-pointer access.
