<show_calendar> should not remove spaces in the answer.

Current Situation

• When using a persistent order with a run-time, then the command

  <show_calendar from="2017-09-04T00:00:00" before="2017-09-07T23:59:59" limit="19999" what="orders" xmlns:ns2="job-chain-extensions"/>
  

  removes n spaces from the OrderId to one space, e.g. an OrderId "a....b" is returned with the answer as "a.b" where . are spaces.

• As a result of this the Daily Plan cannot be created. A nullpointer exception or a unique constraint exception will occur.
• Consider the below linked SourceForge bug report.

Desired Behaviour

• In the answer of the <show_calender> command JobScheduler should return the OrderId as configured including any number of spaces.
