I had encountered an error as below:

The error seems to be related with CB-9189, which was fixed by this apache/cordova-plugin-camera#145.

This PR fixes the case when the CordovaActivity was killed by the android OS while launching another Activity.
This might also fixes #170.

FYI, this NullPointerException can be reproduced by enabling Don't keep activities option in Developer options.
