[Patch Bug 3727] Environment combobox not updated when clicking bullet on toolbar

[Jürgen Spitzmüller]

The attached onliner fixes the issue for me (and Uwe).

Explanation: if current_layout is updated here, the test in LyXView.cpp:462 
returns false and the combo is not updated. Furthermore, current_layout will 
be reset in LyXView.cpp (after the combo update).

OK?

Jürgen
