Merge paraurethral gland and skene gland

From #1243

minor vestibular gland UBERON:0000461

Incorrect superclass: paraurethral gland. This is actually a synonym and not a broader term.

We have these notes:

property_value: external_ontology_notes "in MP female urethral gland, Skene gland and paraurethral gland are exact syns. Note that NCITA seems to use the term in a more generic way, as a parent for skene gland, cowper gland (which may be the same as the male bulbo-urethral gland)" xsd:string {external_ontology="MP"}

Here is NCIT:

   is_a NCIT:C12339 ! paraurethral gland *** 
      is_a NCIT:C32395 ! cowper gland
      is_a NCIT:C49311 ! gland of littre
      is_a NCIT:C61122 ! skene gland

I think NCIT is incorrect in its terminology; 'paraurethral' refers to a particular female gland, NCIT is using it generically. Trying to align with it created a situation whereby we artificially separated paraurethral and skene.

Also of relevance: mgijax/mammalian-phenotype-ontology#1272
