Fixed deleting non-required schemas in search_path

Fixes so that pgsync correctly inserts existing non-required schemas to the search_path

It looks good, but the tests are failing for some not-very-obvious reason...

I did find the reason after all, the qualification of the namespace of the table auditlog_logentry had a syntax problem:

CREATE TABLE "manage.auditlog_logentry" ...

would create a table in the public namespace with the full name manage.auditlog_logentry. The correct syntax would be:

CREATE TABLE "manage"."auditlog_logentry" ...

Though I can see why this was confusing. This changescript was obviously autogenerated by @hmpf , as we don't usually quote names that don't need quoting, so our experience with the quoting rules of PostgreSQL is limited :-D
