Description:

Two different hosts are linked to the same template. When a user changes the time period on Dashboard “A” for one host, the same time period is also applied to Dashboard “A” on the other host.

Steps to reproduce:

1. Go to "Data collection" - "Hosts" - Clone host with templates
2. Go to "Monitoring" - "Hosts"
3. Open Dashboards for hostA and hostB
4. Change time period for hostA for Dashboard A. E.g. "Last 1 day" and click "Apply"
5. Go to Dashboard A for hostB and click "Refresh"

Result:
Same time period applied for hostB's dashboard A

Expected:
Filter time period should not change for hostB
