[FIXED JENKINS-38487] - Jenkins startup must not fail in the case of ComputerListener failure (#2610)
Without this code Jenkinbs startup fails if EnvInject fails to find global property file on startup.
Javadoc says "Exceptions will be recorded to the listener. Note that throwing an exception doesn't put the computer offline." regarding the listener method exception, hence we should not block Jenkins startup
