Deleted and disabled accounts throw a 500 error with no explanation to user

[Netrilix]

This code needs to be rewritten to throw a nice translated error to the end user.

Proposed fix prototype:

if ($e instanceof AccountInvalidException) {
    $this->alerts->addMessageTranslated('danger','ACCOUNT_INVALID');
    $this->logout(false);
    $this->redirect('/'); // This needs to include bath path in the final version
}

New translation messages will need to be added for ACCOUNT_INVALID and ACCOUNT_DISABLED.
