[FOLLOWUP][BUGFIX] Reestablish DB connection in long-running tasks

Reconnecting in isConnected() is not necessary as the next query() will
check the status and reconnect properly if required. Using ping() does
not work with mysqlnd - only if mysqli.reconnect=1 is set. Setting this
is bad practice since a ping() would only reconnect but not properly
reinitialize the charset etc.

Thus a check in Install Tool is added to make sure mysqli.reconnect is
set to "0".
