Fix verse range request when verses are in mixed order

[rkazakov]

Fix verse range request when verses are in mixed order. This is a really strange bug!

Run this request once:
http://localhost:4000/api/v1/Matt3:5-2
Response: verse 2

Run request again:
http://localhost:4000/api/v1/Matt3:5-2
Response: verse 5

I think the correct response in this case should be verse 5. So the logic is:
When the verse range is incorrect (first verse is bigger then the second) ignore the second and return just the first verse. So in the case about should be verse 5 only.
