Found another path to backend init error
There are actually a few different ways to get to this message. 1. Blank state — no previous terraform applied. Start with a cloud block. 1. Implicit local — start with no backend specified. This actually goes through the same code execution path as the first scenario. 1. Explicit local — start with a backend local block that has been applied, then change from the local backend to a cloud block. This will recognize the state, and is a different path through the code in the meta backend. This commit handles the last case. The messaging has also been tweaked. End to end test included as well.
