Akim Demaille a8558bc5a6 diagnostics: don't crash when declaring the error token as an nterm ...

* src/symtab.c (complain_class_redeclared): Don't print empty
locations.
There can only be empty locations for predefined symbols.  And the
only symbol that is lexically available is the error token.  So this
appears to be the only possible way to have an error involving an
empty location.
* tests/input.at (Symbol class redefinition): Check it.
