Simplifying removeAll method.

JobStore.removeAll() iterates through an ArraySet and removes jobs that
satisfy a predicate. The repeated removals will cause ArraySet to do
many System.arraycopy calls and could cause the ArraySet to resize its
internal array several times during the iteration. ArraySet has a
removeIf(Predicate) method which does this exact task without repeatedly
resizing the array or doing many System.arraycopy calls. Switching to
ArraySet.removeIf will reduce the amount of code and improve performance
in some cases.
