Remove unused code in error logger handlers

A long time ago, errors from the emulator itself was sent as
messages that would end up in the handle_info/2 function.
Those clauses in handle_info/2 can be removed.

The code for handling events tagged 'info' instead of 'info_msg'
can also be taken out.
