[native filters] out-of-scope time range filters are triggered multiple times

[graceguo-supercat]

Screenshots

How to reproduce the bug

1. enable dashboard native filter
2. add a few tabs, add a time-series chart in the 2nd tab.
3. add time-range filter component and apply it to 2nd tab only.
4. open dashboard, it shows first tab. but check browser console, you will see time-range filter send out a few /api/v1/time_range/?q= requests.

Expected behavior

1. out-of-scope time-range filter should not be triggered
2. even in the scope, time-range filter should not send multiple requests (i observed that time-range filter right now always trigger multiple requests)

Environment

latest master

@graceguo-supercat I can look into this. In the meantime, these are fairly low cost requests that are mainly validating the time range, so I don't think they pose a major performance bottleneck for dashboards.
