Recurrence(Recurrence.Period.WEEKLY) String Invalid about recurpickerlib

[maltaisn]

There's a two bugs here:

• Recurrence.toString() should return something like "Recurrence{ Every week on the same day as start date }".
• RRuleFormatter should not leave an empty BYDAY attribute when formatting such a recurrence. Note that BYDAY is not required to make a valid RRule.

Both issues should be fixed in 2.1.4. The problem arises from the fact that default weekly recurrence has a special case. By default it has no days set and instead always occurs on the same day of the week as start date's, so the resulting events in RecurrenceFinder.find depends on the start date given. The value of byDay in that case is 1 but that doesn't match any day of the week flag.
