Does not respect act on behalf-of

Problem/Motivation

At present, forum_access will only check forum access permission for the current user, even if a different account is passed into it, due to a missing parameter.

It is possible that an Admin will 'act on behalf' of another user. Access permissions should be checked for the Account passed into Forum access rather than always using the the current user.

Proposed resolution

In forum_access.module , function forum_access_taxonomy_term_access() should pass the $account passed into it to forum_access_access(). At present, it doesnt.
(line 422)

if (!forum_access_access('view', $entity->id())) {
should be:
if (!forum_access_access('view', $entity->id(),$account)) {
