[IMP] web: never select the white color for properties tags

Purpose
=======
Never select the white color for the properties tags, it should be
selected manually, because usually the white color is used to not show
a tag in the kanban view (and that color is never automatically
selected for normal many2many_tags widget).

Fix the alignment of the property label.
