Merge r167656 - [GTK] Crash after getting web view context property with g_object_get
https://bugs.webkit.org/show_bug.cgi?id=131983

Reviewed by Philippe Normand.

The problem is that the getter is using g_value_take_object() and
the default context is destroyed when the caller releases its ref.

* UIProcess/API/gtk/WebKitWebView.cpp:
(webkitWebViewGetProperty): Use g_value_set_object() instead of
g_value_take_object().
