pg_dump dumps extensions in the wrong order

[erichanson]

bundle extension requires the uuid-ossp extension. However, it doesn't explicitly list it as a requirement (because it needs it in a specific schema, which extensions don't support), so pg_dump doesn't know to do the create extension "uuid-ossp" before the create extension bundle. This is doubly a problem because we also can't list it in bundle's .control file because if it's there, it installs the extension in the bundle schema.

This is basically a bug in extensions that we have to figure out how to work around.
