[JENKINS-21911] changing defaultValue of ListSubversionTagsParameterDefinition results in a groovy exception

When I change the defaultValue of a hudson.scm.listtagsparameter.ListSubversionTagsParameterDefinition I got the exception:

groovy.lang.ReadOnlyPropertyException: Cannot set readonly property: defaultValue for class: hudson.scm.listtagsparameter.ListSubversionTagsParameterDefinition

	at groovy.lang.MetaClassImpl.setProperty(MetaClassImpl.java:2435)

	at groovy.lang.MetaClassImpl.setProperty(MetaClassImpl.java:3347)

	at org.codehaus.groovy.runtime.InvokerHelper.setProperty(InvokerHelper.java:183)

	at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.setProperty(ScriptBytecodeAdapter.java:480)

	at Script1.run(Script1.groovy:2.....

With other parameters of a Jenkins job (e.g. strings/text fields) there is no problem with invoking Groovy code like:

job.getProperty(ParametersDefinitionProperty.class).getParameterDefinition("parameterName").defaultValue = "2.6.2"
