gitweb.js: fix null object exception in initials calculation
Currently handleLine() assumes that a commit author name will always start with a capital letter. It's possible that the author name is user@example.com and therefore calling a match() on the name will fail to return any matches. Subsequently joining these matches will cause an exception. Fix by checking that we have a match before trying to join the results into a set of initials for the author.
