[FIX] web_editor: fix missing setDirty prop

Commit [1] removed the protection around the call to setDirty because setDirty
is always defined when the field is initialized through the standard field.js
mechanism. However, in todo_list.js in hr_payroll, the html field is called
without going through that mechanism, resulting in the prop being missing and the
call to fail with a traceback.

This could be fixed by adding the missing prop to todo_list.js, but other people
are likely to do the same mistake in the future so adding a default of our own is
probably better to avoid future similar bugs.
