#2410 - Mode mismatch error when AH mode is changed

When mode of access hub is changed in configuration it shows mode mismatch error on status page of the access hub.

Current AH mode is compared to the mode in last status log and if they are not same it shows the error. When the mode is manually changed in configuration, it should not be considered as an error.
