[minor] address bug with too much in the PRs (#12)

* address bug with too much in the PRs
sets the default branch and checks out the passed branch if it exists
uses those as the base
previously $BRANCH was not being set

* debug the passed branch

* more debugging

* use the remote default branch if it doesn't exist locally

* output the contents of the changed files if we're dry-running
this way we can see what's being changed

* remove debugging from the test workflow

* add newline

* move the newline before the cat
formats nicer
