Impossible to view test details in conformance test GUI

Two of the conformance tests have the same name and get the same ID in the web-report meaning that it is impossible to open the second one (clicking on it will only open the first one).

Tests:

distribution-spec/conformance/01_pull_test.go

Line 174 in 05cf624

    
           g.Specify("HEAD request to manifest path (digest) should yield 200 response", func() {

and

distribution-spec/conformance/01_pull_test.go

Line 186 in 05cf624

    
           g.Specify("HEAD request to manifest path (digest) should yield 200 response", func() {

Apart from giving them separate IDs I would suggest giving them different names to simplify distinguishing them.
