[BUG] Anomaly Charts highlight entire time series as anomaly

[Amatullah]

Describe the bug

For some KPIs, anomaly charts highlight the entire data as an anomaly i.e. in red. The problem occurs in some Drilldowns and DQ graphs too.

Explain the environment

• Chaos Genius version: 0.1.3-alpha
• OS Version / Instance: AWS EC2
• Deployment type: Docker

Screenshots

The overall chart has been highlighted as an anomaly.

In certain places when you zoom the chart exhibits normal behaviour and when you zoom in at other places, the problem persists.

Partially fixed at the frontend side. Need to fix the issues at the backend data ingestion time as well.

@manassolanki can you update on what issues at the backend are causing this? I'll start working towards them.

[Amatullah]

Issue was being caused by having multiple entries in the db for anomaly. Refer issue #451. This has been resolved.
