Context: elgg v2.3.3 + group_tools v9.2.2
Scenario:
- In group tools plugin settings, set 'Allow all users to be invited by e-mail address' to 'yes'
- On 'mygroup' page, click on the 'invite users' button
- Click on 'using e-mail address' tab, enter a valid email address and press 'invite' button
- the 'new user' receives an invitation email, but did not follow the invitation link to create his account
- He creates his elgg account by himself, directly on the site register page
- At his 1st connection, his dashboard is displayed
- The 'group membership' widget displays 'mygroup'
==> But at the same time, the "group invitation" widget displays 'mygroup', if the user clicks on the 'accept' button, an error message saying that he is already a member of that group is displayed
On the other side, in the group invitation page, the pending invitation is still displayed
