ignore non-existent refs in dwim_log()

f2eba66 (Enable HEAD@{...} and make it independent from the current branch, 2007-02-03) introduced dwim_log() to handle <refname>@{...} syntax, and as part of its processing, it checks if the ref exists by calling refsolve_ref(). It should call it as a reader to make sure the call returns NULL for a nonexistent ref (not as a potential writer in which case it does not return NULL).
