Add logging when set status phase with revision return err

[andylibrian]

This function works fine in normal cases. However, when a person
makes a mistake, for example installing different version of CRDs,
the err returned from SetStatusPhaseWithRevision would help tell
what's wrong.

Due to lack of this log, one might have no clue why a chart is
constantly deployed even when there is no change.

In my case, this log helps me to tell that I was on a wrong CRD version:

ts=2020-09-23T04:24:01.763104967Z caller=release.go:517 component=release release=datadog-agent-datadog-agent targetNamespace=datadog-agent resource=datadog-agent:helmrelease/datadog-agent helmVersion=v3 warning="HelmRelease.helm.fluxcd.io "datadog-agent" is invalid: status.conditions.type: Unsupported value: "Deployed": supported values: "ChartFetched", "Released", "RolledBack"" action=upgrade

Note:
There are a few other usages of SetStatusPhaseWithRevision in the same file.
Let me know if we should add logs to the other lines.
