docs(guide/services): minor fixes
docs(tutorial): link update for Jasmine

Jasmine doesn't live at the replaced link anymore.
It has a link to click through, but I figured it would be better
to just go directly to the correct location.

Closes #6591
chore(doc-gen): improve error reporting
chore(doc-gen): fix error-doc processor

The meta-data should be parsed from the name not the id.
