Phase==null not handled

[rmannibucau]

There are several mojo without a phase which fail in current flavor (

maven-profiler/src/main/java/io/tesla/lifecycle/profiler/LifecycleProfiler.java

Line 88 in a1f24a5

} else if (!phaseProfile.getPhase().equals(phase)) {

), would be great to handle them but not sure how it should be reportted.
