Hide method redefined warnings

[Rubyist007]

A few warning messages appear while using Oj.optimize_rails with $VERBOSE = true
Here they are:

.../config/application.rb:23: warning: method redefined; discarding old create_id=

To fix this problem I suggest using the same method that used here:

oj/ext/oj/rails.c

Lines 1041 to 1062 in 8095883

	// rb_undef_method doesn't work for modules or maybe sometimes
	// doesn't. Anyway setting verbose should hide the warning.
	verbose = rb_gv_get("$VERBOSE");
	rb_gv_set("$VERBOSE", Qfalse);
	rb_undef_method(encoding, "use_standard_json_time_format=");
	rb_define_module_function(encoding, "use_standard_json_time_format=", rails_use_standard_json_time_format, 1);
	rb_undef_method(encoding, "use_standard_json_time_format");
	rb_define_module_function(encoding, "use_standard_json_time_format", rails_use_standard_json_time_format_get, 0);
	pv = rb_iv_get(encoding, "@escape_html_entities_in_json");
	escape_html = Qtrue == pv;
	rb_undef_method(encoding, "escape_html_entities_in_json=");
	rb_define_module_function(encoding, "escape_html_entities_in_json=", rails_escape_html_entities_in_json, 1);
	rb_undef_method(encoding, "escape_html_entities_in_json");
	rb_define_module_function(encoding, "escape_html_entities_in_json", rails_escape_html_entities_in_json_get, 0);
	pv = rb_iv_get(encoding, "@time_precision");
	oj_default_options.sec_prec = NUM2INT(pv);
	oj_default_options.sec_prec_set = true;
	rb_undef_method(encoding, "time_precision=");
	rb_define_module_function(encoding, "time_precision=", rails_time_precision, 1);
	rb_gv_set("$VERBOSE", verbose);

Thanks for the cleanup.
