[Stack monitoring] Timepicker doesn't correctly pick defaults values for refresh interval

[estermv]

Kibana version:
main

Describe the bug:
When the user changes the default pause field for timepicker:refreshIntervalDefaults it gets ignored by the timepicker in Stack monitoring unless the value field is also changed

Steps to reproduce:

1. Go to Stack Management -> Advanced settings

2. Change the value for timepicker:refreshIntervalDefaults to

   {
     "pause": true,
     "value": 0
   }
   

3. Go to Stack Monitoring

4. Refresh in the timepicker is still active.

Expected behavior:
Refresh is paused when the default value is true

Any additional context:
The problem could be with this condition

kibana/x-pack/plugins/monitoring/public/application/contexts/global_state_context.tsx

Line 55 in 4b1bf83

if (!value && pause) {

as we check if we need to override values from the data plugin timefilter service to set the defaults for Stack Monitoring ({value: 10000, pause: false}). I'm not sure if we can detect when the defaults have been modified by the user or not.
