Conflict in bbp_unsubscribe action with Buddypress

[SirLouen]

By default, bbp_unsubscribe action works fine both AJAX and link versions

For example:
The subscribe button on top of a forum is an AJAX version
The unsubscribe button in the "subscription" section within a user profile is a link version

By installing Buddypress the AJAX version works fine, but the link version breaks

This can be tested after installing Buddypress by subscribing to a forum and trying to unsubscribe by using the current nonce and the forum ID using the full URL with the adequate parameters (or just by going to the ->members->forums->subscription and trying to unsubscribe by pressing the button.
