Restore append before checking error

[mrodm]

Restore appending results even if there is an error.

For instance, system tests could exit using result.WithError() method and that method could return both results and error:

elastic-package/internal/testrunner/testrunner.go

Line 145 in 6eda8fe

return []TestResult{rc.TestResult}, err
