[FIX] project: deal with corner case in domain_remove_leaf

The method domain_remove_leaf is used to remove leaves from a domain
corresponding to given fields. The particular case ['|', leaf_to_remove,
leaf_to_remove] is replaced by [true_leaf] however the check of the
second element of this subdomain was incorrectly done. This fix
addresses this issue.

Fixes #93225

closes #108164
