Selected slot log filter reset upon client switch

[Eagle3386]

Repro:

1. Successfully add 1 or more client(s) to FAHControl.
2. Select client of your choice.
3. Select Log tab
4. Activate Slot filter (checkbox)
5. Select any slot ID other than 00, e. g. 01
6. Switch to any other client

Result:

1. FAHControl keeps selected tab (Log).
2. FAHControl keeps selected Slot (checkbox stays checked).
3. Actual selected slot is (re)set to 00.

Expected:

1. Upon switching, check if current client's slot ID exists on target client.
2. If it exists, keep selected slot ID (e. g. 01), too.
3. If it's missing, select slot ID 00.
