As @bcmills points out in CL 330253, there is a bug in the package qualification logic of CL 313035. The nominal bug is the use of pkg rather than check.pkg on line 34 of errors.go, but I additionally noticed that our test coverage is not functioning as we expect: testdata error message extraction stops at the first ", so assertions in check tests that were checking that imports were qualified were not actually checking anything.

Opening this as a release blocker for tracking purposes. I'm fixing now.

This is a partial port of https://golang.org/cl/330629, containing
only the actual bug fix and adjustements to another test file.

The respective test case has not been ported yet as it requires
some bigger adjustments.

For #46905
