Crash when requesting encryption

[HenryHu]

Steps to reproduce on Nexus 7 with 1.4.0.7:

1. create a new note
2. select menu
3. choose "encrypt"
4. a dialog pops up, asking for oi safe
5. rotate the screen

It seems like that when the screen is rotated, the presence of OI Safe is not checked before running it.

The report says that: Unable to instantiate activity null: java.lang.NullPointerException

Stack trace:

@cragrim I think your problem is related to #15
