Ruby exception constructor bugfix

The Ruby exception constructor is modified to accept 0 arguments, which is
how Thrift library code creates exception objects. Without this fix, Thrift
Ruby clients that receive exception objects crash.

The call to super (resolving to ThriftStruct#initialize) is retained, but
is called with the default value (an empty hash) instead of passing the
message along.
