Fixed error messages from DROP VIEW to align with DROP TABLE

- Produce a "Note" for all wrongly dropped objects
  (Like doing DROP VIEW on a table).
- IF EXISTS ends with a list of all not existing objects, instead of a
  separate note for every not existing object.

Other things:
 - Fixed bug where one could do CREATE TEMPORARY SEQUENCE multiple times
   and create multiple temporary sequences with the same name.
