Potentially fix intent crash

[SystemKeeper]

We got a few reports about a crash in donateSendMessage from TestFlight. I am not sure how this can happen and I am unable to reproduce locally. Two things

1. Split the image part to 2 lines, so we know which call fails if it fails in the future
2. Make sure to do the donation before dismissing the share view (should probably have a completion block, but as a first step this makes sense)
