Move InitClassLoader from JNI_OnLoad to LoadGlobalClassReferenceHolder

Browse Source 
This fixes clients with custom JNI_OnLoad code. This is basically a
reland of https://webrtc-review.googlesource.com/21281, but called from
LoadGlobalClassReferenceHolder instead of InitGlobalJniVariables. The
problem it solves is that some clients call InitGlobalJniVariables
from a strange thread and without using the rest of our Java API.
