Skip issue reporting for features/sanity specs

What does this MR do and why?

Skips reporting if the spec is in qa/specs/features/sanity/ as these don't test the app but the framework. These are skipped with the SKIP_REPORT_IN_ISSUES variable in sanity jobs but it needs a further check in other jobs.

Fixes an error in failure issue reporting:

`partial_file_path': undefined method `[]' for nil:NilClass (NoMethodError)

Ex: https://gitlab.com/gitlab-org/quality/nightly/-/jobs/3281887773

We only expect api or browser_ui in the file path, not sanity.
