remote set-head: refactor for readability

Browse Source 
Make two different readability refactors:

Rename strbufs "buf" and "buf2" to something more explanatory.

Instead of calling get_main_ref_store(the_repository) multiple times,
call it once and store the result in a new refs variable. Although this
change probably offers some performance benefits, the main purpose is to
shorten the line lengths of function calls using this variable.
