Pre-installation check does not check version of the database

[BernhardEriksson]

There are several comments in the forum from people have not been able to install v4 but not knowing why. Since other checks are made I suggest adding a check for mysql/mariadb version to the pre-installation check to reduce the number of reports of this.
