org-resolve-clock loops over all open org buffers for detecting open

it should just loop over the org-agenda-files.
I was working on an extension for clocking and was recording my testing results
into a separate org file. I also had put there examples of
various clock lines to test regexps against. The example clock lines
effectively prevented me from clocking in to a task from my normal
Since org has so many usages, I think it should not be assumed that each
org buffer is related to the agenda functionality.
