Back to 1.10 after building

... this still breaks the release build but I want to encourage us to get it working before we release again.
Update gradle.properties
0.16.2-SNAPSHOT
Merge branch '0.16.x' of https://github.com/mattrjacobs/RxJava into 0.16.x
Merge pull request #801 from mattrjacobs/0.16.x

Added more possible failure cases to CompositeExceptionTest
Add testMultipleWithSameCause UnitTest

Also make tests capable of failing with timeouts. Before the constructor would immediately go into an infinite loop and hang the tests.
