Sibling Conveys with identical message causes template failure in UI

[mdwhatcott]

...when you have 2 or more Convey statements with the same message (in my case as siblings) the tests will show just three question marks in the UI.

Looking at the stack trace unfortunately doesn't provide much more insight, as the only relevant line number I could find was the close of the top most Convey statement. The only way I found this error was by slowly narrowing the scope of what tests were being run using comments, then taking blind shots in the dark.

It would be very nice if a more explicit error message was presented in this case.

347 mentions this issue and suggests a panic in the case of duplicate sibling tests.

I think it DOES panic the test binary, but the UI shows a nonsensical message like the following image:

Here's the code to repro:

package something

import (
    "testing"

    . "github.com/smartystreets/goconvey/convey"
)

func TestBad(t *testing.T) {
    Convey("Bad", t, func() {
        Convey("Inner", func() {})
        Convey("Inner", func() {})
    })
}
