Custom dashboards set as Home remain so after update

the problem: 

The Custom Home dashboard is not home after the upgrade. It's our Home is a Home again. this not a good way for people who modified dashboard 

STR: 

1. Install PMM
2. Create a new dashboard  and make it Home dashboard  (https://community.grafana.com/t/change-home-dashboard/7441) 
3. Update PMM (by button)

Expected results: 

• The New dashboard id still - Home dashboard, so default.

Actual result: 

• default Home dashboard shipped with PMM is  Home for now.  
• however  - The New dashboard is alive and working, just not  Home 

The use case: 

I'm DBA and I need some specific View on the Databases, so I've modified dashboard and need it to be a  Main what user (developers) will see.  The best way to do this  for me is  -make this dashboard -  Home   

But the moment I've updated PMM server .. I need to set up my Dashboard as Home one more time and do this every update
