httpd: consistent default branch

The test suite for `radicle-httpd` assumed that `master` would be used
for the working copy. However, if a user set their Git default branch
to be something other than `master` then the test suite will fail for
them.

To remedy this, initialise the working copy with the `master` branch
as well.
