fix(CreateChatView): hide the Contacts label when no contacts

- hide the TagSelector's `listLabel` and disable the `textEdit` when the
  contacts model is empty
- add forgotten `qsTr()`
- remove some no-op positioniers/anchors/width/height bindings (these are
  handled automatically for QQC2 Control's header and contentItem)
