Smaller issues

[phwiget]

• when the field extension (Fix, Reserve, Symptom) is updated and the medication PUT, the change is not reflected in the database
• if a medication has a planned end date (dispenseRequest.validityPeriod.end), after PUT without any change the copy created has the start date set to the previous end date and no end date anymore. In addition, all dosage texts are lost (integrated into the stop reason -> see below)
• the end date is generally ignored (if entered newly), same for stop reason and status
• upon PUT: all note are added together (stop reason and instruction). However, when entering a medication in Elexis, instructions and stop reason are separate note
