Fix lax comparison in validation tests (#7815)

If you add t.Logf("%+v %+v", actual, testCase.expectedErrors) to
the test code, you'll notice that only Errors' Messages are being
compared:

    --- PASS: Test_ValidURLValidation/Invalid_schema (0.00s)
    binding_test.go:43: [Url] [Url]

FieldNames and Classification are ignored in comparison.

Moreover, an Errors slice with a single Error with empty message
is formatted as '[]' (the same as empty slice), which is also
error-prone. I discovered this when working on #7791 when one test which
was not supposed to pass did pass. https://play.golang.org/p/qC4wVLrm4NG

This commit changes the test to do the comparison properly.
