This count should mean the number of fields expected in the serialized form,
so if some fields are skipped, they shouldn't be counted
Methods affected:
- Deserializer::deserialize_tuple
- Deserializer::deserialize_tuple_struct
- VariantAccess::tuple_variant
Without this, if it fails, the only information printed is useless:

Panics lead to reporting errors in tests inside of serde_test internals,
returning errors moves the report location to the corresponding assert_tokens
expression
Fixes these being treated as "tests" by `cargo test` in serde_derive:
