Fix slow op on refreshSubscriptionTab + restart the agent on jetbrain…

…s and agent's user id mismatch (#284)

## Test plan 
- put a breakpoint in `addNewSubscriptionTab` and set `agentUserId` a
dummy value so it mismatch the `jetbrainsUserId`(that will test the
error handling)
  - internal ide error should not appear 
- agent should restart and a new proper matching id should be assigned

- in `addNewSubscriptionTab` increase the timeout & runIde
  - UI should not freeeze 🥶
