[Security Solution][Detections] - EQL preview not receiving expected response

[yctercero]

Kibana version:
7.11

Describe the bug:
When trying to preview an EQL query in rule creation/edit, Kibana blows up. This is because we are expecting rawResponse to include the meta object that includes all the info needed to fill out the inspect functionality. It is currently typed as a field guaranteed to be there, but as search strategy is something actively being developed, seems some updates have been made. More information is needed.

Steps to reproduce:

1. Click to create rule in detections
2. Add EQL query any where true
3. See Kibana error

Expected behavior:
When previewing EQL query, histogram should successfully resolve.

Errors in browser console (if relevant):
