I'm not able to switch to Sqlite data source via Akonadi configuration UI.
It does not save my settings and shows me always MySQL source when I close and reopen configuration UI.

It makes some changes in akonadiserverrc BUT it does not help - it can not start with Sqlite dataseource.

Looks like it also write wrong information in  ~/.config/akonadi/akonadiserverrc
After  I submit new settings via UI it changes file content like this:
[Debug]
Tracer=null
[%General]
Driver=QSQLITE3
[QMYSQL]
..................
[QPSQL]
.............
[SQLITE]
Name=akonadi

BUT IN ORDER TO GET IT WORK I have to alter this configuration by
removig:
[SQLITE]
Name=akonadi

And replace it with:
[QSQLITE3]
Name=/home/mylogin/.local/share/akonadi/akonadi.db

PLUS after several config updates via UI I've found multiple records in akonadiserverrc:
[%General]
Driver=QSQLITE3
[%General]
Driver=QSQLITE3


Reproducible: Always

Steps to Reproduce:
I'm use russian locale but hope that this is not related.
1. Open Akonadi server configuration
2. Switch to SQLite source
3. Close Configuration window
4. Open it again

Actual Results:  
Configuration shows me MySql as source for Akonadi

Expected Results:  
It must show me SQLite related configuration
