AVRO-2302 Fix invalid namespace on BigQuery import
This change fixes an issue when importing Avro files into BigQuery, when
such files have been generated using `ProtobufData`. The schema
namespace may end in a dollar sign, if using nested classes.
The correction piggybacks on the fix provided for AVRO-2143 (#283). In
it, `SpecificData` will attempt to load a class joining the namespace
and the name with a dot, and if that fails, it tries again with a dollar
sign.
The same behaviour is hereby reused for `ProtobufData`.
> ReflectData should determine inner class names in a different way.

>
> I used ReflectData to generate schemas containing inner classes. These
> classes were named automatically by ReflectData with dollar ('$'), with, for
> example com.company.avro.House$Type. Nevertheless @AvroAlias does not support
> aliases containing '$' in names. In particulr, it fails in validateName in
> Schema core class. The failure is correct given that AVRO name specs does
> notinclude the '$' symbol.
> I suppose that ReflectData should, for example, generate inner class names in
> a different way, such as replacing '$' by dots ('.'), or it should fail.
> And a detail: Although I cannot add aliases with '$', I can still encode and
> decode such objects and inner classes using that schema.
> I think that it newer versions it is also happening.
