[FIX] calendar: getting recurrent_ids twice

The `_search` is override in `calendar.event` to return both ids and
virtual ids of recurrent events. Calling `.get_recurrent_ids` after the
search is wrong.

The entire request has been copied from the original
`_find_allowed_model_wise` function defined in `mail.message` to ensure
his correctness.

The purpose here is to ensure every virtual event id is mapped to the
real event id so the original function doesn't throw KeyErrors for
virtual ids.
