Review comments:

1. How about the method name "has_symbols?" instead of "has_any_symbols?"

2. convert_serialized_symbols_to_strings method

This method checks "if attr.object_class == Hash"
Even though we have used only Hash type objects for serialized attributes, can't I have an array defined as seriazed attribute? For ex: "serialize :my_attr, Array"
Should this method hence also support Array objects as well? What if I said "serialize :my_attr, String" or some other db supported object?
Should this method intead omit this check and invoke "if self.class.has_any_symbols? attributes[colname]" for all cases or all supported cases?

3. Please add the below additional tests to ArvadosModelTest -> test "refuse symbol keys in serialized attribute: #{x.inspect}"
