Description of problem:

The default host bookmarks like active, disabled, error etc are always recreated even if I delete them. We should keep them deleted if user decides to delete those.

Version-Release number of selected component (if applicable):

How reproducible: when the audit record about the deletion gets cleaned up

Steps to Reproduce:
1. visit the all Hosts page, list bookmarks
2. delete one by "Manage bookmarks"
3. make sure the audit record about the deletion gets removed (cleaned up), e.g. by setting some value to Setting[:audits_period] and run foreman-rake audits:expire
4. run foreman-rake db:seed

Actual results:

the bookmark is created again

Expected results:

it should not be recreated

Additional info:

we can no longer rely on audits (cleared after some time), we should probably split db:seed and initial setup data.
