Let MinUnitAccessMode return correct perm (#18675)

Browse Source 
- Don't let `TypeExternalTracker` or `TypeExternalWiki` influence the
minimal permission, as they won't be higher than read. So even if all
the other ones are write, these 2 will ensure that's not higher than
read.
- Partially resolves #18572 (Point 1,2,5?)
