https://nodejs.org/api/packages.html#exports contains «All paths defined
in the "exports" must be relative file URLs starting with "./" .»

Prior this change the property

  ATTENDEE=CN="Ж 4 <>'^':":mailto:[email protected]

is read as:

  jCal: [
    'attendee',
    { cn: `Ж 4 <>'":` },
    'cal-address',
    '":mailto:[email protected]'
  ]

The value starts with quote, which is wrong.

Evolution creates instances of events, which contain RRULE and RECURRENCE-ID
without RANGE parameter.  Since the RANGE is not THISANDFUTURE, but absent,
such events do not recur.

When EXDATE is in DATE format and DTSTART is DATE-TIME, then
to determine whether a ocurrence shall be excluded, the
occurence shall be converted to DATE and then compared to EXDATE.

This applies also for the very first EXDATE, when it coincides with
DTSTART.

iCalendar and vCard parameters do not use \ as escape character in the
property parameter values, hence cn="\"X" is not a quote X, but invalid.
The proper escape character is ^ per RFC 6868.  This change replaces
helpers.unescapedIndexOf(x,…) with x.indexOf(…) in order not to

… as \ is no escape character there.  When the propery parameter
contains :, then it must be quoted, the colon cannot be escaped.

As the function stringify.propertyValue in fact stringifies
property parameter values, it is renamed accordingly.

When iterating with
  e is an event-component
  if (e.isRecurring() {
     let i = e.iterator();
     while (n = i.next()) {
       o = g.getOccurrenceDetails(obj)
       …
     }
  }

on the first iteration the DTSTART instance shall be returned.  It is returned,
when there is RRULE.  In the lack of this change, on the first iteration, when
RDATE is present without RRULE, the first RDATE instance is returned.
