db name from connectionstring is not used

[kmpm]

When using a connection string for mongodb where the database is provided AND leaving
db commented out in config the plugin still uses myApp as database name.

mongodb.ini

; ... lost of earlier stuff
string=mongodb://usr:passwor@mongoserver:27017/haraka
;db=myApp

; ... lots of later stuff

In this case I would expect harakato be used as db name.
