[Bug fix] Re-prioritize commit interrupts (#1170)

Browse source 
This change will check commit interrupt signal coming from other channels, e.g. newHead, reSubmit, before checking transaction level interrupt. This is to fix a corner case where an interrupt signal coming from another channel getting intercepted by transaction level interrupt, which resulted in an uncleaned state (potentially deadlock).
