Query Node: Council term numbering causing issues (`electedCouncilId`)

## Problem
When using the query node with the following query:
```query MyQuery { electionRounds { id isFinished referendumStageVoting { id startedAtBlock } referendumStageRevealing { id startedAtBlock } endedAtBlock electedCouncilId electedCouncil { electedAtBlock endedAtBlock id } cycleId } }```

there is a problem with `electedCouncilId` in that for the first few elections it returns normal numbers but upon reaching 9 switches to `0000000a`, `0000000b`, `0000000c` and so on.

I do not understand why it does this but it has caused problems with Dapplooker.com (the dashboard team that builds us dashboards which shows view of council spending etc)
