forceCfg is applied only after the installation

[mudrd8mz]

The forceCfg allows to force some CFG values by hard-setting them in the config.php. I have it set to something like

    "forceCfg": {
        "prefix": "m_",
        "debug": 32767,
        "debugdisplay": 1,
        "divertallemailsto": "my@dev.account.tld",
        "themedesignermode": 0
    },

But I realized that mdk install still uses the default prefix. The reason is that forceCfg is applied after the DB installation. It would help if it was injected into config.php before it - so that things like $CFG->prefix and others are taken into account.
