ci-automation: fix broken result indicators in test reports

The CI automation test report library used embedded images to indicate
test success / failures. The URL these images were referenced from has
gone AWOL some time ago, resulting in ugly "missing image" references in
test reports.

This change updates the test result indicator code to only use emojis.
