sync: Correct imports of `R_HEADS` and `HEAD`
`R_HEADS` is imported twice, from both the git_refs and project
modules.
It is actually defined in git_refs, and in project it is imported
from there, so the import of `R_HEADS` from project in the sync
module is redundant. Remove it.
`HEAD` is imported from project, but like `R_HEADS` it is actually
defined in git_refs. Import it from git_refs instead.
