After accepting invitation from group profile, link to group is incorrect

[bree-z]

I've confirmed the bug reported in https://cboxopenlab.org/groups/help-forum/forum/topic/bug-incorrect-url-generated-when-accepting-group-invite/

Logged in as teststudent, I navigated to the profile of https://openlabdev.commonsinabox.org/groups/13er-club/ and clicked 'Accept Invitation'.

I saw the message that the invitation was accepted: "Group invite accepted. Visit 13er Club." The link was: https://openlabdev.commonsinabox.org/%22https://openlabdev.commonsinabox.org/groups/13er-club//%22

I don't think I've ever accepted an invitation this way, so I'm not sure I've ever seen this message before now! But I don't think the link to the group makes much sense, since you're already there. Perhaps we just remove the second sentence?

This is due to an issue with the way that quotes are being escaped. It should be fixed in cedfc2e.

This looks good, thanks!
