If they move out and you purchase with vacant possession then that does properly end the tenancy.
However, it's unlikely they will do this as sitting tenants have much stronger protection against eviction and some fall under the Rent Act which means they'll be paying a much less than market value rent.
Don't purchase the property either
1) Till you are 100% the tenant is no longer in the property
2) You can afford to take the lower rent and still make a profit
Also bear in mind that the next buyer if you were to sell would face the same problems
