Error hidden with info log level and status body too long

[raffis]

This is partially related to #190.

If many manifests are in a repository and one of these manifest got an error the error is not visible in info log level because you end up seeing:

{"level":"error","ts":"2020-12-14T09:52:40.719Z","logger":"controllers.Kustomization","msg":"unable to update status after reconciliation","controller":"kustomization","request":"flux-system/k8s","error":"Kustomization.kustomize.toolkit.fluxcd.io \"k8s\" is invalid: status.conditions.message: Invalid value: \"\": status.conditions.message in body should be at most 32768 chars long"}

However if the log level is debug the real error is visible before that in the debug msg Normal.
The error should be visible in all log levels despite seeing body too long error.
