Why did the Apollo 7 and 8 missions not have to make the 'transposition and docking manoeuvre'?

Neither mission carried a lunar module, so there was nothing to carry out the docking manoeuvre with. Having said that, they did carry out the transposition part of the manoeuvre, separating the command module and turning round to rendezvous as if they were going to dock with the LM. On Apollo 7 this revealed a flaw in design. The shroud for the Lm was originally to open up like a flower, but on Apollo 7 they found one of the panels had not properly opened, which would have caused trouble had they had to extract a lunar module. On all subsequent flights the cover was jettisoned completely.
