fix(geoip-location): Fix error handling in downloadGeoIpDatabase

[teogeb]

The code inside this if statement was never run:

if (!isDbFileValid(dbFileInDownloadFolder, remoteHash)) {
    try {
        fs.rmSync(downloadFolder, { recursive: true })
    } catch {
        // ignore error when removing the temporary folder
    }
    throw new Error('Downloaded database hash does not match the expected hash')
}

The isDbFileValid method was async but the call doesn't await it. Therefore the if clause was always false.

Fix

Modified to isDbFileValid to be a sync function as there was nothing async in in the implementation.
