Do not overwrite values in attribute form while SearchMode

Because it can be in SearchMode during editing state, a change of selection in the feature list would overwrite the values of the selected one by the one selected before. This because the widget-values were not resetet for the current feature and are saved.

The saving is not avoided, because on edit, and switching to SearchMode and changing selection, the old feature still have to be saved. But it does reset the values of the current widget in SearchMode after changing selection - even if it's not visible by the user - to avoid to have wrong values there.
