-----------------
- Changed default to `False` for parameters `checkMayViewEvent=False` and
`checkMayViewComment=False` of `utils.getLastAction`, this way, we get last
action even if current user may not, and it is quicker.
This fix a performance issue in `ImioWfHistoryAdapter.historyLastEventHasComments`
when called several times.

- In `utils.getLastAction`, parameter `action` may be `before_last` and will
return the before last action if it exists.
