Adoptions need to respect year in parameter

[opoudjis]

The current implementation of bsi is assuming, in the case of the adopted parameter, that the year will be supplied in the adopted identifier value. It must not: the year in the identifier call overrides it, and we have documents where the adopted identifier is not given with a year.

So:

Pubid::Bsi::Identifier.create(number: 639, adopted: Pubid::Cen::Identifier.parse("EN ISO 639:2012")).to_s == 
"BS EN ISO 639:2012"

but:

Pubid::Bsi::Identifier.create(number: 639, year: "2013", adopted: Pubid::Cen::Identifier.parse("EN ISO 639:2012")).to_s ==
   "BS EN ISO 639:2013" # (currently is "BS EN ISO 639:2012")
Pubid::Bsi::Identifier.create(number: 639, year: "2013", adopted: Pubid::Cen::Identifier.parse("EN ISO 639")).to_s == 
  "BS EN ISO 639:2013" # (currently is "BS EN ISO 639")
