InfluxDB 2: Cannot find authorization by user

[bednar]

The Internal Server Error occurs when I try find authorizations by userId.

# Create authorization

# Delete authorization

<-- 204 No Content http://127.0.0.1:9999/api/v2/authorizations/053a1903d5f19000 

# Find authorization by `userId`
--> GET http://127.0.0.1:9999/api/v2/authorizations?userID=053a17f5ac719000
<-- 500 Internal Server Error http://127.0.0.1:9999/api/v2/authorizations?userID=053a17f5ac719000 
<-- {"code":"internal error","message":"key not found"}

Steps to reproduce:

1. Create authorization
2. Delete this authorization
3. Find authorizations by user

Expected behavior:
Return authorizations for user.

Actual behavior:

INFO: <-- 500 Internal Server Error http://127.0.0.1:9999/api/v2/authorizations?userID=053a17f5ac719000 (2ms)
INFO: {"code":"internal error","message":"key not found"}

Environment info:

• InfluxDB version: docker v2.0.0-beta.3

Probably caused by #16818
