QUARTZ: Incorrect next execution time

[Blemicek]

The next execution for QUARTZ cron expression * 1 * * * ? at 2019-01-01T00:01Z should be 2019-01-01T01:01Z not 2019-01-01T00:01:01Z.

I believe that 2019-01-01T00:01:01Z is the correct next execution time for that cron expression.
You specified * as the value for the seconds, so it should match every second of minute 1 of every hour of every day of every month of every year.

Wild-cards (the ‘*’ character) can be used to say “every” possible value of this field.

You should use 0 1 * * * ? if you intend to only get the minute 1 of every hour of every day of every month of every year.

I submitted PR #397 with tests for the two expressions 0 1 * * * ? and * 1 * * * ?
