fix(ci-info): detect GitHub Actions before presence-only CI providers [SDK-7081]

getCiInfo() checked Jenkins first on mere presence of JENKINS_URL/
JENKINS_HOME, so a self-hosted GitHub Actions runner with leftover
Jenkins env vars was classified as Jenkins with build_url undefined.
obs-api force-disables the TRA Re-run control for builds without a CI
build_url, greying the button. Move the explicit GITHUB_ACTIONS check
ahead of the presence-only providers.

Also return after resolve({}) in getGitMetaData when no git directory
is found, instead of falling through.

Adds getCiInfo unit coverage: GHA detection, the Jenkins-shadowing
regression, pure Jenkins, and no-CI.
