GUI unable to refresh Requirements

[J0B10]

Just want to document this so I don't forget about it.
I'll try to do some more investigations on what happens tomorrow.

Description

When setting the new IntegerRequirement from PR #148 to a noninteger it fails and displays the message Unable to set the requirement., just as intended.

But if you then try to refresh the Requirements using Show Requirements the get request fails without an error message.

To fix it use Delete for the IntegerRequirement that you previously set to an illegal value.
Then Show Requirements works again.

So here my results rom debugging:

When setting a Parameter to an invalid value deserializing it will throw an exception, jusat as intended.
The problem is that the requirement content is set before deserialzing the value:

chatoverflow/src/main/scala/org/codeoverflow/chatoverflow/configuration/ConfigurationService.scala

Lines 290 to 301 in a25d1c2

	try {
	val reqContent = loadedRequirementType.get.newInstance().asInstanceOf[io.Serializable]
	requirements.getAccess.setRequirementContent(requirementId, reqContent)
	reqContent.deserialize(content)
	logger info s"Created requirement content for '$requirementId' and deserialized its content."
	true
	} catch {
	case e: Exception =>
	logger error s"Unable to instantiate requirement content. Exception: ${e.getMessage}"
	false
	}

So if deserializing the value throws an exception the requirement content will be set to a parameter witch cannot be deserialized cause the value is null.

Fixing this should be as simple es moving the call of deserialize() before setRequirementContent().
