Remove the trailing dot at the end of the failing spec

When a test is failing, the reporter adds a trailing dot to the test title. This dot is not added to the passing tests report so the programmer tends to add it manually at the end of the test title. So, when failing, two dots are displayed.

Looks like this breaks the spec filtering link as well. Story here: https://www.pivotaltracker.com/story/show/58043244
