Make FSTIntegrationTestCase Objective-C++ (#439)

* Make all FIRLogger functions extern "C"

* Make FSTIntegrationTestCase Objective-C++

Keep external interface to FSTIntegrationTestCase Objective-C

* Add explicit dependency on Firebase/Community/Core from Tests

This fixes a linkage error on a missing _FIRSetLoggerLevel symbol
