Tables: fixed "resize to default" of multiple stretch column (added 3b3503e, broken 7a61f340).

Browse Source 
Fixed a warning.
Storing RightMostStretchedColumn column for resizing code.
Avoid clearing RightMostEnabledColumn in BeginTable() so resizing code can potentially use it.
(Added regression tests for resize all to default imgui_dev)
