Fix context loss in QOpenGLWidget upon tlw change with AA_ShareOpenGLContexts 

The logic introduced in 2ea90c56 has an issue: it resets (destroy the
context and co.) upong TLW change even when AA_ShareOpenGLContexts is set,
and that is just wrong and goes against what the docs claim.

Fixes: QTBUG-74307
