Before this commit, when a many2one's input shows the choice
"No records", the dropdown does not close.
Cause:
When blurring, the many2one will select its first item. In our case,
"No records" is not selectable and it will not close the dropdown.
How to reproduce:
- go to a form view with a many2one field
- insert a non-existent value in the many2one ("No records" is displayed)
- leave the many2one input ("blur" event)
Result before:
The dropdown containing "No records" is still open.
Result after:
The dropdown containing "No records" is closed.
