Bug 11392: (follow-up) fix syntax error in template

In the two FOREACH loops introduced by the patch, wrap
the module and action names with quotes.  This fixes a
problem where parsing the template crashes with the following
error:

  Template process failed: file error - parse error - .../viewlog.tt line 83: unexpected token (RETURN)
    [% FOREACH actx IN [ ADD DELETE MODIFY ISSUE RETURN CREATE ] %] at .../C4/Templates.pm line 132.
