Fix issuable state indicator

Now the issuable reference check works only in project scope, if we
reference an issuable from a non-project resource (e.g. epics), then
project is not set, and there is mismatch in generated issue references.

This patch enables issuable reference state check also from group scope.

Closes gitlab-ee#4683
