Purge negative id on selection when commit

[beltegeuse]

• You select added features (they have negative id).
• You commit change (commit attribute positive id to added features) but your mSelectedFeatureIds haven't updated and have always negative Id in mSelectedFeatureIds.
• If the user doesn't reselect features, you have a segmentation fault because if you do a iteration on mSelectedFeatures there are wrong id.

Possible solutions :

• Erase all negative ids in commitChanges

Advantage : easy to do

Disadvantage: user's selection change when he commit

• Provider return new id of added feature and replace in mSelectedFeatureIds.

Advantage : no change for user when he commit.

Disadvantage : more change to do in code.
