Setup wizard does not take into account optional dependencies when ordering plugin installations

Seen this myself, and also reports from others that Jenkins requires a restart after setup wizard plugin installation for things to not be broken.

Steps to reproduce:

1. Install suggested plugins in setup wizard
2. Observe that Folders is installed before Credentials
3. New Item, type Folder

Expected result

Folder config screen loads

Actual result

It does not

Workaround

Restart Jenkins after plugin installation.
