Fix potential crash opening 3.0 blend files in older versions. 

Affects insertion of constraints in liboverrides. In some cases, when
opening newer post-3.0 .blend files, the source won't be found anymore,
override apply code then needs to fail properly instead of crashing.

Related to refactor from  rB33c5e7bcd5e5.
