NPE in IabHelper in v. 0.9.8.7

[nkuznetsow]

I use OpenIAB v. 0.9.8.7 from this https://mvnrepository.com/artifact/org.onepf/openiab/0.9.8.7
In Fabric I have seen many crashes like this:

Fatal Exception: java.lang.NullPointerException
       at org.onepf.oms.appstore.googleUtils.IabHelper$1.onServiceConnected(IabHelper.java:248)

The last version of IabHelper class in master branch I unable to find onServiceConnected method body on line 248. I think, that this class was rewrote. If it true, please, release the new version of the lib to fix this crach.
