Boolean settings don't take boolean values as valid

[baco]

My testing minimal init.vim

let g:completion_matching_ignore_case = v:true
let g:completion_matching_smart_case = v:true
let g:completion_trigger_on_delete = v:true

How to reproduce
Load some file and completion won't take those settings into account.

Expected behavior
Complete using the set options (matching_ignore_case, matching_smart_case and trigger_on_delete) as when setting them to 1 instead of v:true
