log preferences can't be updated when viewing revision ranges

[Christian Boos]

For e.g. log:branches/1.0-stable?revs=14482-14483, we generated the following HTML:

<form id="prefs" action="" method="get">
        <div>
          <input type="hidden" name="action" value="stop_on_copy">
          <input type="hidden" name="revs" value="<trac.versioncontrol.web_ui.log.RevRanges object at 0x7fd9da09a210>">
                                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Needless to say, pressing Update will lead to an error page.

(0.12-stable doesn't have the problem, 1.0-stable and trunk do)

Aha! Didn't know about r13919 (slowly catching up with the great stuff that happened while I was off duty ;-) ).

Fix should be trivial:

Fix committed in [14487], merged to trunk in [14488].
