impact: error stack traces are difficult to read

Experienced: When I enable "Show Links In Log" it causes the error stack traces to be incorrectly formatted. This only happens when the step has the setting enabled. If the setting is disabled, the log is formatted correctly.

For example:
11:24:41,302 WARN - NOTE - This is a Build Trigger Step. You must click on the "Triggered Build" link in the step graph to jump to the build you want.
11:24:41,302 ERROR - Step 'master>Send some Slack Messages' is failed: java.lang.NullPointerException: Cannot invoke method getId() on null object at org.codehaus.groovy.runtime.NullObject.invokeMethod(NullObject.java:77) at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:45) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:42) at org.codehaus.groovy.runtime.callsite.NullCallSite.call(NullCallSite.java:32) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:42) at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:54) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:112) at script15251312457031833429650.run(script15251312457031833429650.groovy:6) at com.pmease.quickbuild.plugin.basis.BasisPlugin$32.evaluate(BasisPlugin.java:382) at com.pmease.quickbuild.DefaultScriptEngine.evaluate(DefaultScriptEngine.java:305) at com.pmease.quickbuild.D...
11:24:41,457 INFO - Executing post-execute action...

Vs the correct formatting:
11:24:41,302 WARN - NOTE - This is a Build Trigger Step. You must click on the "Triggered Build" link in the step graph to jump to the build you want.
11:24:41,302 ERROR - Step 'master>Send some Slack Messages' is failed: java.lang.NullPointerException: Cannot invoke method getId() on null object

Expected: The log should display the correct formatting no matter what the setting is to show links in the log.

Repro:
1. Create a step
2. Enable the "Show links in log" setting
3. Create an error in the post-execute action
4. Run the build
5. Observe the incorrectly formatted log
6. Edit the step
7. disable the "show links in log" setting
8. Load the log again and observe the log is now correctly formatted.
