This commit properly removes the Many2ManyTagsField and
Many2ManyTagsAvatarField's placeholder when at least one tag has been
selected.
Steps to reproduce:
- In Contacts, open a partner's form view
- Edit and set at least one "tag"
- The placeholder is present next to the selected tags
Note: the placeholder was already present in previous versions.
