MDL-41446 Completion: Incorrectly marks complete when grade data present with no actual grade
MDL-42582 Availability: Restriction display incorrect for multi-para Labels

When a label has multiple paragraphs, its name (converted to plain text)

accept the line feed, this caused incorrect display on the course page
when that label is shown as a requirement for accessing another activity.
MDL-33536 navigation: hide hidden categories from the navbar
MDL-42723: Hide and handle LDAP error when user not in context being checked

MDL-41304 only fixed the case when 'Search subcontext' is enabled. We need to
fix the case when it's not enabled too.

While silencing errors with an @ should be avoided if possible, there's no
other way to prevent the warnings in this case.
