Branch keeps reference to old Activity instance

[sabvente]

Hello,

The InitSessionComplete method gets called on wrong Activity instance.

Repro:
Branch_Testbed_Android project with SDK upgraded to 7.0.2 (lib 4.3.2)

• Add Finish() to the end of InitSessionComplete
• Run app
• New instance of MainActivity is created (instance A)
• InitSessionComplete gets called on instance A
• Press home button
• Open app from launcher
• New instance of MainActivity is created (instance B)
• InitSessionComplete gets called on MainActivity instance A
