After #3767 landed, there were a bunch of rustfmt::skips added to ChannelManager that could easily be removed.

Here we pick some of that low-hanging fruit by removing the skips for methods that are less than ~5 lines long.

We also remove skips from all cfg(async_payments) code since as the feature owner I know that's safe from unwanted rebase conflicts.

rustfmt::skips were added recently all over channelmanager in order for

Here we remove a bunch of those skips that aren't necessary because the

In the previous commit we formatted a bunch of short methods. Here we clean up

This code is not at risk of unwanted rebase conflicts, so the skips can safely

After #3767 landed, there were a bunch of rustfmt::skips added to ChannelManager that could easily be removed.

Here we pick some of that low-hanging fruit by removing the skips for methods that are less than ~5 lines long.

We also remove skips from all cfg(async_payments) code since as the feature owner I know that's safe from unwanted rebase conflicts.
