Disallow deletion of CurrentExtensionObject while running extension script.
While the deletion in itself wouldn't break things, any further creation
of objects in the script would result in dangling pg_depend entries being
added by recordDependencyOnCurrentExtension(). An example from Phil
Sorber convinced me that this is just barely likely enough to be worth
expending a couple lines of code to defend against. The resulting error
message might be confusing, but it's better than leaving corrupted catalog
contents for the user to deal with.
