Activating an already-activated account gives an unhelpful message

[boonebgorges]

The generic 'There was an error activating your account, please try again.' might be a little bit smarter.

I need this for a project so I will likely find time to patch it for 1.3, unless someone else grabs it.

There were two places where the activation process did a bp_core_redirect, so the patch removes one of them and returns to let the second handle the activation error. The patch is against the 1.2 branch.

I did not test this in single site to see what error messages were returned. For network activation error messages also see ​https://core.trac.wordpress.org/ticket/15780.
