Proposal name changes, cause duplicate proposals and obsolete official url

[voodoorai2000]

Some proposals change name throughout amendments.

For example:
This proposal: Proposición de Ley sobre aguas canarias. (122/000174)
used to be called: Proposición de Ley sobre delimitación de los espacios marítimos de Canarias (122/000174)

Mark the old proposal manually as closed with status "Subsumido en otra iniciativa en el Congreso." and update the official url to point to the related proposal in agoraonrails.
