fixed bug with onprem creation of taxonomy groups.

1) termStore.GetGroup(groupId) does not work. had to use termStore.Groups.GetById(groupId) instead.

2)also removed creation of new guids for each group/termset/term. this was causing the subsequent terms to not find the group and termset already created.
Added GetTermGroupById
