Description

Fix another crash-on-exit

Easily reproducable:
* Load project, wait for it to load
* Change CMakeLists.txt, do not save
* Build project
* Immediately close KDevelop

Backtrace (reduced):
5  0x00007f5f092b7345 in KDevelop::ProjectBaseItem::appendRow
(this=0x2425560, item=0x67255a0) at
/home/krf/devel/src/kdevplatform/project/projectmodel.cpp:421
6  0x00007f5f0ec4dad2 in KDevelop::ProjectPrivate::reloadDone
(this=0x5f0d2b0) at
/home/krf/devel/src/kdevplatform/shell/project.cpp:160

The hunk in void Project::close() fixes a consecutive crash:
