Nach einem WebView-Reload lebt die native SQLite-Connection weiter.
createConnection() warf dann 'Connection netdiag already exists' -> initDb()
brach ab -> onMount im Layout brach ab -> die App haengt ewig auf
'NetDiag startet...'.

Fix: vorhandene Verbindung per isConnection/retrieveConnection wiederverwenden,
nur oeffnen wenn noch nicht offen.
