Story (Required)

As a developer using image-updater, I want to make sure all packages and commands are fully tested.  We should add tests to verify their expected behavior.

Current unit test coverage in pkg/image: 70.27%
credentials.go: 69
image: 78
kustomize: 0
matchfunc.go: 100
options.go: 84
version.go: 39

Acceptance Criteria (Mandatory)

• analyze the current unit test coverage in pkg/image
• add unit tests so that all testable code paths are covered
• code blocks that are not testable by unit tests under the current testing framework can be exempted
