Subject: Fix #10225 (Instance := {} accepts duplicate fields)

This replaces the mismatched context error, which occurred when
Instance := {} was used with strictly more fields than declared.

Since we later check that field names match those declared for the
instance, now that we reject duplicates we know that there are no
extra fields.
