Fix: Custom lockscreen force close

https://paranoidandroid.atlassian.net/browse/AOSPA-140

Attempting to create a blurred image on first run causes a force close
if an image wasn't first selected. Have the user crop the current wallpaper
for use in such cases.

I've never been able to reproduce the problem on Hammerhead, Mako or
Grouper, so I can't guarantee that this solves it.

Feedback is needed from a user that constantly experiences this bug.
