Akregator corrupts the opml file and crashes, always.

[wens]

[Impact]

Without this fix, Akregator can start crashing on initialization and corrupt data. Without a backup, this means data loss, and it also means a non-working Akregator.

[Test Case]

1. Launch Akregator and create a handful of feeds.
2. Restart Akregator several times.

Nothing should happen, but it will crash sometimes.

[Regression Potential]

Little to none. The contents of the if (app.isSessionRestored()) conditional is the same with the exception of the window being initialized before Akregator is restored.

[Original Description]

I noticed that Akregator started to crash on initialization. Then I noticed that it had corrupted to a small size my RSS feed file.

Bionic ships with a fixed version, Artful does not.
