wiki linking does not work consistently for all item types and wiki formats / #3691

NOTE: This task was formerly titled: "Not all item types displayed in wiki in two formats #number item:number"

Not all item types are displayed in wiki in two formats
#number and item:number. Some works only in first, some on the second, and some on both.

There is a list of different items linked in wiki in three formats:

1. #number
2. [[item:number]
3. [[name]]
