MBS-7074: Do not show current entity in 'relate to' autocomplete

08407e6b3ac92 refactored Autocomplete.js and preserved the idea of a
resultHook, but it was never placed in the options declaration. This
meant the resultHook could only act as identity, but we need to override
it for the "Relate to..." drop down. This commit moves it the options
section so that it can be overriden.
