4bd3d4b148 app/vminsert/netstorage: do not return error from storageNode.flushBufLocked when the buffer has been successfully re-routed to healthy nodes

c7f3e58032 vmalert: avoid sending resolves for pending alerts (#498) 
Before the change we were sending notifications to notifier
if following conditions are met:
* alert is in Fire state
* alert is in Inactive state

We were sending Inactive notifications to resolve alert ASAP. 
Unfortunately, we were sending resolves for Pending alerts that become
Inactive, which is wrong.

In this change we delete alert from the active list if
it was Pending and become Inactive. In this way we now
have Inactive alerts only if they were in state Fire before.
See test change for example.
