fix: Avoid side effect

[gaocegege]

Signed-off-by: Ce Gao [email protected]

What this PR does / why we need it:

Fix #531

We will meet an error during the creation and retry it again and again. I strongly suggest using state compare pattern instead of current state machine based implementation. But it is another topic.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #

Special notes for your reviewer:

Thanks. This is a required change. I was about to give the comment in #496 before it got merged :)

[gaocegege]

@johnugeorge Yeah my mistake. I did not find this potential problem. And when I am running unit test in #528 I find the logic has bugs.
