Title:
  Undo of Create Collection doesn't work

Status in Zorba - The XQuery Processor:
  Fix Committed

Bug description:
  In the following query an error is raised during the PUL application.
  As a consequence the m:aaa collection should be destroyed.
  However in UpdCreateCollection::undo() when GET_STORE().deleteCollection(theName) is invoked, theName contains a NULL pointer, thus no collection is deleted.
  The following query thus returns m:aaa as being available.

  import module namespace m = 'xqueryzorba.org/test/xqddf/ic' at '/zorba/pulsrc/test/rbkt/Queries/zorba/xqddf/ic.xqlib';
  import module namespace ddl = "http://www.zorba-xquery.com/modules/store/static/collections/ddl";;
  import module namespace dml = "http://www.zorba-xquery.com/modules/store/static/collections/dml";;
  import module namespace dddl = "http://www.zorba-xquery.com/modules/store/dynamic/collections/ddl";;
  import module namespace ic_ddl = "http://www.zorba-xquery.com/modules/store/static/integrity_constraints/ddl";;

  ddl:create($m:empc);

  ic_ddl:activate(xs:QName("m:ic_simple"));
  try
  {
  (
  dddl:create(xs:QName("m:aaa"))
  ,
  dml:insert-nodes($m:empc,
  <emp>
  <salary>600</salary>
  </emp>
  )
  );
  }
  catch * {}
  dddl:available-collections()
