NightlyBase doesn't convert string in dayOfWeek param

No conversion is made of the value in dayOfWeek if it's a string. The
value is directly passed to croniter without proper conversion.
This fix handles both single string values and multiple comma separated
values as well as abbreviation in the string. ("0" "5,6" "0,fri" et.c.)

The extra `- 1` here caused single blank lines to be skipped when
chopping un-requested lines of the end of a response.  Earlier tests,
even if they had actually been running, would not have discovered this
as they did not test blank lines.  Fixes #3101.
