MNG-5288 prevent NPE, not all ProjectBuildingException instances have
getResults()
I have a reproducible scenario, cannot currently update/reopen MNG-5288
our in-house plugin is calling MavenProjectBuilder.buildFromRepository()
which causes this problem for the case of a parent pom that is not of 'pom'
packaging. (someone uploaded the wrong metadata apparently)
```
org.apache.maven.project.InvalidProjectModelException: Some problems were
encountered while processing the POMs:
[ERROR] Invalid packaging for parent POM
com.atlassian.plugins:remote-link-aggregator:2.0.13, must be "pom" but is "jar"
@ com.atlassian.plugins:remote-link-aggregator:2.0.13

com.atlassian.plugins.rest:atlassian-rest-module:jar is missing. @ line 84,
column 21
