multiple choice question : importing a codeList + adding a "precise" sets the "precise" to the previous modality

[QRuhier]

• create a multiple choice question
• import a code list (csv)
• add a "precise" to any modality (let's say the index X)
• visualize : the precise is set on the wrong modality (X-1)
• refresh Pogues and open again the question : the precise is indeed placed on the modality X-1, but its id has not changed

Nb :

• there is no bug if you create the code list instead of importing it
• there is not this bug on single choice question
