[SnackBar] Enforce vertical layout when action text is too long

The snack bar content layout is by default horizontal, and we only change it to vertical when the action view is too wide and ellipsizes the message text. Therefore if the layout orientation is already vertical, we should just keep the layout and no need to check if the message text is multi-line again.

Resolves #1876
