Creating a single record using a sub-pattern on a O2M field breaks imports

[kevinkhao]

Scenario: You have two models, Parent, and Child

Parent has a O2M field called Children

You want to express that some Parent "Alice" has a Child named "Bob"

You import an excel file with something like: children_ids|1|name#key Bob

Expected behaviour: If Bob doesn't exist, a Child is created and linked to Alice (this works) If Bob exists, nothing should happen ==> This crashes

Crash occurs only when two conditions are met:

• there is only one O2M record that is found by key
• there is no operation on this unique O2M record
