[Bug]: No User-Visible Error When Conflicting Placements for a WButton Groups

[wallstop]

Description

Right now if you specify two different placements for a WButton Group, it picks the first one, and the user doesn't know, resulting in a confusing user experience.

Steps to Reproduce

1. Create a WButton with group "Test" pinned to the top
2. Create a WButton with group "Test" pinned to the bottom

Expected Behavior

The UI tells you you messed up

Actual Behavior

Both WButtons are pinned to the top with no warning.
